Summary: PHP-FPM Dies after self-initiating reload
-Status: Assigned
+Status: Feedback
Type: Bug
Package: FPM related
Operating System: fc7
PHP Version: 5.3.2
Assigned To: fat
New Comment:
I can't reproduce the problem.
I tried to compile 5.3snap on rhel 5 server with libevent 1.1.14 and I
have no
problems.
Two questions:
1- does the bug appear when sending a USR2 signal to the master process
(reloading) ?
2- Can you compile the static modules (mysql, pspell, ...) as shared
modules so
that you will be able to run FPM without any module to check if there is
no bugs
running a specific module with FPM.

Can you also provide the libevent version and the OS you're using.
Thanks

value
; of '0' means 'Off'.
; Default Value: 0
emergency_restart_threshold = 10
; Interval of time used by emergency_restart_interval to determine when

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;
; Multiple pools of child processes may be started with different
listening
; ports and different management options. The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools
which
; FPM can handle. Your system will tell you anyway :)
; Start a new pool named 'www'.
[www]
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific
address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses
on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000
; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
listen.backlog = -1
; List of ipv4 addresses of FastCGI clients which are allowed to
connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the
original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each
address
; must be separated by a comma. If this value is left blank, connections
will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web
server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0666
;listen.owner = nobody
;listen.group = nobody
;listen.mode = 0666
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default
user's group
; will be used.
user = phpfm
group = phpfm
; Choose how the process manager will control the number of child
processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on
the
; following directives:
; pm.max_children - the maximum number of children that
can
; be alive at the same time.
; pm.start_servers - the number of children created on
startup.
; pm.min_spare_servers - the minimum number of children in
'idle'
; state (waiting to process). If the
number
; of 'idle' processes is less than
this
; number then some children will be
created.
; pm.max_spare_servers - the maximum number of children in
'idle'
; state (waiting to process). If the
number
; of 'idle' processes is greater than
this
; number then some children will be
killed.
; Note: This value is mandatory.
pm = static
; The number of child processes to be created when pm is set to 'static'
and the
; maximum number of child processes to be created when pm is set to
'dynamic'.
; This value sets the limit on the number of simultaneous requests that
will be
; served. Equivalent to the ApacheMaxClients directive with
mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the
original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 30
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers -
min_spare_servers) / 2
;pm.start_servers = 20
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
;pm.min_spare_servers = 5
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
;pm.max_spare_servers = 35
; The number of requests each child process should execute before
respawning.
; This can be useful to work around memory leaks in 3rd party libraries.
For
; endless request processing specify '0'. Equivalent to
PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
pm.max_requests = 250
; The URI to view the FPM status page. If this value is not set, no URI
will be
; recognized as a status page. By default, the status page shows the
following
; information:
; accepted conn - the number of request accepted by the pool;
; pool - the name of the pool;
; process manager - static or dynamic;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes.
; The values of 'idle processes', 'active processes' and 'total
processes' are
; updated each second. The value of 'accepted conn' is updated in real
time.
; Example output:
; accepted conn: 12073
; pool: www
; process manager: static
; idle processes: 35
; active processes: 65
; total processes: 100
; By default the status page output is formatted as text/plain. Passing
either
; 'html' or 'json' as a query string will return the corresponding
output
; syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php
extension or it
; may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status
; The ping URI to call the monitoring page of FPM. If this value is not
set, no
; URI will be recognized as a ping page. This could be used to test from
outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load
balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php
extension or it
; may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping
; This directive may be used to customize the response of a ping
request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong
; The timeout for serving a single request after which the worker
process will
; be killed. This option should be used when the 'max_execution_time'
ini option
; does not stop script execution for some reason. A value of '0' means
'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout = 300s
; The timeout for serving a single request after which a PHP backtrace
will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_slowlog_timeout = 10s
; The log file for slow requests
; Default Value: /var/log/php-fpm.log.slow

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0
; Chroot to this directory at the start. This value must be defined as
an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used
whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =
; Chdir to this directory at the start. This value must be an absolute
path.
; Default Value: current directory or / when chroot
;chdir = /var/www
; Redirect worker stdout and stderr into main error log. If not set,
stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Default Value: no

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are
taken from
; the current environment.
; Default Value: clean env

; Additional php.ini defines, specific to this pool of workers. These
settings
; overwrite the values previously defined in the php.ini. The directives
are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines
which can

'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be
overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or
no.
; Defining 'extension' will load the corresponding shared extension
from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will
not
; overwrite previously defined php.ini values, but will append the new
value
; instead.
; Default Value: nothing is defined by default except the values in
php.ini and
; specified at startup with the -d argument
