OpenLDAP crash under barracuda query

The problem appear just after I installed a barracuda V400 and configured the LDAP verification for a valid recipients.

On the server the process just died. At the end of the log I was able to see things like this:

Jul 25 06:30:24 XXXXXXXXX slapd[8327]: daemon: read active on 94
Jul 25 06:30:24 XXXXXXXXX slapd[8327]: daemon: epoll: listen=7 busy
Jul 25 06:30:24 XXXXXXXXX  slapd[8327]: daemon: epoll: listen=8 busy
Jul 25 06:30:24 XXXXXXXXX  slapd[8327]: daemon: epoll: listen=9 busy
Jul 25 06:30:24 XXXXXXXXX  slapd[8327]: daemon: epoll: listen=10 active_threads=0 tvp=NULL
Jul 25 06:30:24 XXXXXXXXX  slapd[8327]: daemon: epoll: listen=11 active_threads=0 tvp=NULL
Jul 25 06:30:29 XXXXXXXXX  slapd[8327]: daemon: activity on 1 descriptor

Jul 25 06:30:29 XXXXXXXXX  slapd[8327]:

I opened a case at barracuda support and after few check with their engineer they told me this was a known issue with the Exchange Antivirus.

So the solution they provided me was to disable the exchange antivirus, in our case this was not a problem, we just don’t have exchange.. I probably just havn’t seen this option during my initial setup..

 

So to disable this option go to ADVANCED => Exchange Antivirus:

Check the “No” radio button for “Enable Exchange Antivirus” to disable it. At this time our LDAP haven’t crashed since this change..

Hi all! I'm a 27 years old guy from Quebec city, Canada. I've been playing with Linux since 1998 and start to earn my life using Linux and FOSS around 2005. Since then I've earned few certification and courses including CLP10 (Certified Linux Professional from Novell), RHCE (RedHat Certified Engineer) and JBOSS Administration course. I'm a Linux sys admin and I'm working here in Quebec city for a small company who are RedHat Advanced partner since few years. So I'm trying to always keep me updated on new technology and new RedHat product. The best way I've found to do it is to use and contribute to the Fedora Community. So I've joined the community in mid 2009 as a Fedora Ambassadors, I still learning how everything work in a opensource community, but I really liked what I saw at the 2009 FUDCON in Toronto.
