Dovecot users,
  I guess I should complain to Redhat.  Their latest rhl release of 
Dovecot is 1.0.rc15 on redhat 5.   Its even older if you are running on 
redhat 4 which ironically is much more stable.  I even tried to run 
dovecot directly to ldap using userdb ldap, but that would fail after a 
few minutes.  We are now downloading and installing 1.010.  So far it 
appears to be stable, but we shall see over the rest of the afternoon.  
Too early to judge.  I hate having to run source code installs, but it 
may be the only way in this case.  I guess I would expect better from a 
commercial linux company in the stability of what they release.


ATRPMs.net keeps up to date rpms for RHEL 3, 4 and 5...

For 5 is here:

[Dovecot] Dovecot too many open files???

[Tim Tyler]

Dovecot experts,
 We just recently deployed Dovecot 1.0.rc15 on a Redhat 5 system.  I 
have over 1400 users.  At first it appeared to work fine.  But soon, 
we had complaints of students that couldn't retrieve their email.  I 
looked in the logs and found this error.


Jan  7 22:27:31 stu dovecot: auth(default): 
pam(pucklisl,144.89.40.6): pipe() failed: Too 
many open files


We are running Dovecot to authenticate via pam which authenticates ldap.

Below is the output of

Any solutions for this problem?
