My buddy and I found
#define DB_LDAP_MAX_QUEUE_SIZE 1024
in the db-ldap.h file in the source.
We believe we hitting this threshold for some reason. So, we are
looking to increase this to 8192. However, when trying to build the
RPM source from atrpms, I get this:
# rpmbuild -ba dovecot.spec error: line 1: Unknown tag: %bcond_without inotify
Any help?

Any idea how to stop this?
I have about 5 Thousand users using horde that login ever 1-5
minutes to refresh their page. I assume it is a setting, but I am
confused as to why it doesn't happen almost right away. It seems
to take some time to build up.Please help! This is taking my webmail system down hourly.
dovecot -n?
Hunch is login_max_processes_count is too low. http://wiki.dovecot.org/LoginProcess
