http://issues.apache.org/bugzilla/show_bug.cgi?id=43966 Summary: internal dummy connections blocking httpd Product: Apache httpd-2 Version: 2.2.6 Platform: Other OS/Version: Linux Status: NEW Severity: major Priority: P2 Component: All AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] We have apache freezing with internal dummy connections (on https default vhost) apparently closing down forever. Using mod_status I get __C_CKCC__CWCCWC__C__KCC_CC_CC____C__K__W____C__CCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC [...] CCCCCCCCCCCCCCCCCCCCCCCCCCCW_CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC That means that most of the processes are "C" Closing connection. [...] 12-1 17525 1/449/2424 C 6.07 1275 0 0.0 8.39 40.93 127.0.0.1 web.xxx.com GET / HTTP/1.0 13-1 17526 1/237/2215 C 4.65 3507 0 0.0 2.87 29.31 127.0.0.1 web.xxx.com GET / HTTP/1.0 If I do strace a process, for example 17526 I see that is reading from a socket # strace -p 17526 Process 17526 attached - interrupt to quit read(356, <unfinished ...>^C Process 19023 detached and if I use lsof -p 17526 to see what is fd 356 I get: apache2 17526 apache 356r FIFO 0,6 82466795 pipe When every process is in status "C" the server no longer responds, and doing graceful or restart gets even worse for load rockets high and machine gets unstable. I've found a workaround: writing rubbish in the pipe (eg: cat /etc/passwd > /proc/17526/fd/356 frees all the children and resumes the apache), but that's not a solution :) HTTPD: Server version: Apache/2.2.6 (Unix) Server built: Nov 20 2007 22:05:17 Server's Module Magic Number: 20051115:5 Server loaded: APR 1.2.11, APR-Util 1.2.10 Compiled using: APR 1.2.11, APR-Util 1.2.10 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr" -D SUEXEC_BIN="/usr/sbin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf" running this way: /usr/sbin/apache2 -D DEFAULT_VHOST -D PHP5 -D SSL -D INFO -d /usr/lib/apache2 - f /etc/apache2/httpd.conf -k start Thanks in advance for any help. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
