I have strange overload problem. I have Zimbra/8.6.0_GA_1194, most of time load is very good, about 0.5 (we use Ubuntu 14.04) But then load come to 5-7 and server totally freezes, we all use IMAP and we cannot send emails. I get errors like:
ERROR [ImapSSLServer-4840] [ip=x.x.x.x;oip=x.x.x.x;via=x.x.x.x(nginx/1.2.0-zimbra);ua=Zimbra/8.6.0_GA_1194;] mailbox - Failed to lock mailbox
imap - Exception occurred while handling connection
It happens 3-4 by day. What could be the problem?
