Yeah, it's the memory killing you.
I'd suggest the following:
Disable the logger package:
zmprov ms SERVERNAME -zimbraServiceEnabled logger
- Edit the zimbra crontab, remove zmlogprocess and zmgengraphs
- Cut down the frequency of zmstatuslog and zmdisklog
Edit amavisd.conf.in and reduce max_servers
Reduce zimbraLmtpNumThreads (via zmprov) on the server
Disable the spell server, or reduce the number http processes (in conf/httpd.conf, spareservers, minspareservers, maxspareservers - reduce to 2 or 3) |
