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,<http://144.89.40.6>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
[root at stu ~]# dovecot -n

Any solutions for this problem?

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.
