We have ZCS 5.0.1 Open Source edition which has been running smoothly for more than three months now. Tonight, all email deliveries were deferred and tailing the zimbra.log file revealed this error:
Googling around I found its something that amavis plays up with BDB. I disabled Antivirus check and still the problem did not resolve.TROUBLE in child_init_hook: BDB no dbS: Lock table is out of available locker entries,
I killed amavis manually and restarted zimbra services via zmcontrol. Things are back to normal now.
But I am worried if this will happen again. Bugzilla says the status is fixed here with the last post being Build: Release 5.0.3_GA_2048.RHEL4_20080303184202 RHEL4 NETWORK edition - apparently its fixed in this version.
Is this right?
