On a tip-off that IMAP logins were failing intermittently but frequently,
I discovered that our OpenLDAP server was running out of file handles:
May 25 11:26:10 mussel slapd[27058]: warning: cannot open
/etc/hosts.allow: Too many open files
May 25 11:26:10 mussel slapd[27058]: warning: cannot open /etc/hosts.deny:
Too many open files
Restarted slapd to fix, and added a 'ulimit -n 4096' at the top of
the init.d script to reduce the likelihood of this happening.
