When I strace I get:
------
select(1, [0], NULL, NULL, {1789, 240000}) = 1 (in [0], left {1782, 750000})
time(NULL) = 1069768897
read(0, "a1 login username password\r\n", 4096) = 22
socket(PF_UNIX, SOCK_STREAM, 0) = 11
connect(11, {sin_family=AF_UNIX, path="
/var/state/saslauthd/mux"}, 110) = 0
writev(11, [{"\0\6username\0\004password\0\4imap\0\0", 22}], 1) = 22
read(11, "\0\2", 2) = 2
read(11, "OK", 2) = 2
----
another thing that seems odd in your strace is that it looks like it tries to connect to a mysql instance, then it tries to check the /etc/password file, then it reports no database selected.... are you using an MySQL auxprop?
I know it's probably already been checked, but I show similar problems when saslauthd isn't running correctly...

I have managed to strace the 'looped' imap process. I did the following. Restarted cyrus and opened a mailbox with squirrel. Started STrace on the pid. I then opened mail until the imapd process started using all available cpu cycles. This is the strace output:

At this point the last line repeats indefinitely. The only output from the trace that has been editored is the password, changed to 'password'. Any Ideas of what the problem is?

Quoting [EMAIL PROTECTED]:
Greetings
I have been setting up a new cyrus-postfix-amavis(new)-spamassassin system
and have come across a problem. Cyrus master starts without problems. I can send
messages and I can usually view the message. But for some reason, after
viewing a few messages the imapd process starts using 100% of CPU.
Unfortunately there is very little other info that I can send. The imapd.log
shows nothing unusual. The only entry that resembles a problem is
Nov 24 15:09:13 xserverii imapd[10410]: SQUAT failed to open index file Nov 24 15:09:13 xserverii imapd[10410]: SQUAT failed
but after a google or two it seems that this is normal.
Messages logs shows nothing unusual. Neither does maillog or auth.log.
I can always reproduce the problem by using squirrel mail (outlook also shows
shows the same problem so it is not a client problem) by going though the
first 6 emails. Before the end of the list the problem presents itself (sometimes
on message one, but usually I can view a few before the problem starts).
All software (cyrus/postfix) are the latest stables as of a few weeks ago.
The system is RH8.0.
I have tried to use gdb in an attempt to offer something more in this request
but have been unable to obtain any useful info (this is the first time I have
attempted used gdb seriously, so its mostly my ignorance that is the problem).
Any ideas of how to track this problem down would be most welcome.
Regards Warren
