I am recieving an error message after 2-3 days of uptime when using squirrelmail (horde works fine).
I either get: "ERROR: Unknown IMAP response." or "ERROR: Connection dropped by IMAP server.", this happens for all users of the server. The server load is minimal.
I saw a post on http://mailman1.u.washington.edu/pipermail/imap-use/2005-December/000056.html
with the same symptoms, and the answer was to fix squirrel mail [
http://mailman1.u.washington.edu/pipermail/imap-use/2005-December/000060.html ], or slow the imap server down. The problem goes away when I `strace` the imapd process, which in effect slows down the imap server.
Anyone know the proper way to fix this issue?
