Hello,
I need major assistance. We have a dual cpu w/ 2GB of RAM. Recently, lmtpd and imapd processes have been eating up all available memory to the point the machine stops responding. I have try to reconstruct every mailbox and fix the mailbox database, but nothing has fixed it. Some of the ctl_ commands fail too by eating up memory. None of the users have very large mailboxes either. Any help would be great. Thank you.
Setup:
6600 Accounts
Redhat 9.0
Cyrus IMAPD 2.1.16
Cyrus SASL 2.1.10
OpenLDAP 2.1.23
Sendmail
