Posted this on the wiki forums, but in case anyone's cruising this who
may have some ideas/possible solutions.
I keep getting defunct/zombie processes building up when using cacti
(graphing program for snmp and weather data or anything else) which
calls mysql and imapproxy (for use with mail server).
Having searched a lot it seems a v.rare condition but it seems these
packages make regular calls to mysql and imapproxy which don't get
removed by the kernel reaper. clamav does it a little too.
Wher I'm getting my guesses from:
This would appear to be an issue (v.rarely again) on debian 2.4.18
special kernels (so maybe this one too) or libc6 on ppc. Its maybe
because I've updated something a while ago I shouldn't have.
More annoying than critical - have to run a cron job to kill/restart
offending mysql every few hours.
