After installing the latest kernel update (from 6.Aug) and rebooting, I'm now getting hunderds of mysqld zombies (defunct) one some servers. I don't really see why yet... the only thing which changed was the kernel... The mysqld is a self-compiled one.
FYI, after reverting to the old kernel, everything is running fine again.
En résumé:
With: k_smp4G-2.4.21-238.rpm -> zombie problems (kernel-51547 patch) With: k_smp4G-2.4.21-231.rpm -> fine.
If you need more details, please feel free to ask.
Can you run strace -f on the mysqld one and look for /proc/ files it opens ?
After fixing my database corruption mysql seems to run fine again - I am still having problems with amavis-milter under SuSE 8.2 pro though which have appeared since the new kernel update. Can not see that it is opening any proc files though:
[SNIP] Correction on that - I just rebooted again and the mysql zombies are back so I am downgrading back to 2.4.20-115 as 2.4.20-118 creates too many problems. For some reason the mysql problem only comes up straight after the reboot, if you stop mysql after booting with rcmysql stop leaving it down for a couple of minutes and then starting it up again with rcmysql start does not let you reproduce the problem under 8.2.
