hi all,
i've cyrus-imap, cyrus-sasl, postfix and mysql+web-cyradm installed on OSX.
logging is turned on for apache, mysql, postfix & cyrus
when i click on a particular link ('accounts') in web-cyradm, my CPU pegs @
100%.
here's what (little) i know
(a) the following error in apache error log:
PHP Notice: Undefined index: action in /var/www/WebCyrAdm/index.php on line
111, referer:
http://testserver.internal.testdomain.com/webcyradm/index.php?action=editdomain&domain=virtual1.internal.testdomain.com
(b) my CPU monitor rises to 100% utilization
(c) my browser just 'cycles' endlessly
(d) 'top', strangely, shows nothing above ~5% CPU
(e) *no* errors are shown in mysql, postfix or system logs
(f) on execution of the accounts link, i *do* see the following in my
cyrus-imap log:
imap[507]: executed
imap[506]: refused connection from ::1
now, i'm not certain it's relevant, but cyrus-imap *is* compiled w/ libwrap, and
/etc/hosts
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
10.0.0.6 testserver.internal.testdomain.com
and,
/etc/hosts.allow
ALL: ::1 127.0.0.1 172.30.11.0/255.255.255.248
(g) in order to reclaim CPU, i have to 'kill -9' the cyrus-imap 'master' (NOT
the postfix master ...) process. originally, i thought it was killing off
mysql, but it's apparently correlary?
(h) some of the time -- not 100% reproducibly -- killing off the master process
causes something else (dunno yet) to die off as well, such that none of my
console processes respond ... e.g., a simple 'ls' does simply nothing.
hard reboot is then required.
this looks like an issue with an attempted/failed connection to the cyrus imapd
socket invoked by clicking on the web-cyradm accounts link ... but that's as
far as i've drilled down.
this seems to be a many-body problem specific to the combination of webcyradm,
postfix and/or cyrus-imap -- as exim + vexim + cyrus-imap were fine w/ *no*
socket issues that i noticed.
any ideas where the problem *starts*?
