dovecot - Jul 2008 - imap-login: socketpair() failed: Too many open files

Hi,

I'am trying to use heartbeat to start dovecot...

It starts but all the login connections are reject with this line on log file:
Jul  7 12:47:28 markov dovecot: imap-login: socketpair() failed: Too many open
files

No username/password are asked (using Thunderbird as client).

Outside heartbeat, dovecot runs fine.

My environment:

# dovecot --version
1.1.1
# uname -a
Linux markov.impa.br 2.6.18-53.1.21.el5xen #1 SMP Tue May 20 10:03:27 EDT 2008

Any suggestion?

Sounds like heartbeat leaks its file descriptors to Dovecot processes.
I'd suggest fixing heartbeat.
