IMAP/mysql errors in /opt/zimbra/log/zimbra.log
I was digging through the zimbra log this morning as I am using imapsync and I am seeing the following:
442 WARN [ImapServer-4519) [ ip=127.0.0.1;firstname.lastname@example.org;] sqltrace - Connection pool is 75% utilized. 27 connections out of a maximum of 34 in use. Turn on debug logging for zimbra.sqltrace to see stack tracess of connections not returned to the pool.
Is this an IMAP limit, or mysql limit? Also, is there a way to increase the limit from 34, to a higher number. Or is this a warning I can ignore? I've also seen some that say 34 connections in use. Could anyone help me with this?
