Hi Friends, One of our client getting these types of LFD messages :- [QUOTE]------------------ Starting Dovecot Imap: Warning: fd limit (ulimit -n) is lower than required under max. load (100 [ 1000), because of default_client_limit [ OK ] Starting Dovecot Imap: Warning: fd limit (ulimit -n) is lower than required under max. load (100 [ 1000), because of default_client_limit Last died with error (see error log for more information): fcntl(F_GETFD, -1) failed: Bad file descriptor [ OK ] Starting Dovecot Imap: Warning: fd limit (ulimit -n) is lower than required under max. load (100 [ 1000), because of default_client_limit Last died with error (see error log for more information): fcntl(F_GETFD, -1) failed: Bad file descriptor [ OK ] Starting Dovecot Imap: Warning: fd limit (ulimit -n) is lower than required under max. load (100 [ 1000), because of default_client_limit Last died with error (see error log for more information): fcntl(F_GETFD, -1) failed: Bad file descriptor [ OK ] ------------------
I have gone through different forums and post but couldn't get exact solutions on this. While restart dovecot at first time I got an error like this :- [QUOTE]----- -bash-4.1# service dovecot restart Stopping Dovecot Imap: [FAILED] Starting Dovecot Imap: Last died with error (see error log for more information): fcntl(F_GETFD, -1) failed: Bad file descriptor [ OK ] -----
After executing this command again it started ok. Can you please let us know why such errors occurs? P.S. At the file /etc/security/limits.conf there is an line for dovecot soft limit and hard limit which was set to 40000. Please assist !!

  Hello :) Could you check to see if Shell Fork Bomb Protection is enabled in "WHM Home " Security Center " Shell Fork Bomb Protection"? Thank you.

  I notice there has been no reply to this. I'm in the same situation. I have Shell Fork Bomb Protection enabled. What else should I check for?

  Try disabling Shell Fork Bomb Protection and see if the issue persists. Thank you.
