[Dovecot] Using Dovecot new version 2.0.13 facing issues.

[गौरव जोशी]

Hi,

I have configured POP-IMAP server with dovecot 2.0.13 with mysql support.
When I am running load test on the same I face issue on IMAP connections. I
get "dovecot: imap-login: Error: fd_send(imap, 15) failed: Interrupted
system call" followed by "dovecot: imap-login: Internal login failure" in
log files.

Below is my dovecot -n output;
=========================================================
# 2.0.13: /usr/local/etc/dovecot/dovecot.conf
# OS: Linux 2.6.18-238.el5 x86_64 CentOS release 5.6 (Final)

  }

}

}
=========================================================

Please help I want to move this server in live environment.

Have a nice time,
