ISA Firewall Service stops unexpectedly

Hi Guys. I have an interesting situation that has occurred a number of times recently to which I cannot seem to find out any information on when searching the net. Having spent some time google’ing the event log errors, I have decided I need the expert advice of you guys.

The situation is, Small Business Server 2003 R2 Premium running ISA 2004 which has been in and running for nearly a year recently started to have Firewall Service crashes. These I have noticed looking back through the logs only occur when either the scheduled backup runs at around 10:30pm or during the Exchange cleanup operation scheduled for around Midnight.

The logs below have been extracted in time order from either the System or mostly Application Logs.

I have been unable to see if I can manually restart the RRAS service during the backup procedure or exchange cleanup operation, but I can manually Start the service the following morning without any problems at all.

I will mention that I have been receiving a considerable amount more Allocated Memory Alerts which I once fixed by following a KB article  -  I thought this could possibly be related so thought I’d mention it.

Please find the logs I have extracted below. Any assistance on this would be greatfully appreciated.

Kind Regards,

Nigel

Hi
It looks like the connection between ISA FW service and MSDE database used for loging is responsable. You can try an temporary solution to prove that by changing the loging type of ISA FW. For that you have the info here

Many Thanks Dan. I will give this a try later on today. Meanwhile, Is there any possible way of finding out what Is actually causing the connection failure as it looks like the same problem is causing SBS Monitoring to fail as well.

Many Thanks,

Nigel

I wonder if your server is OK wih memory consumption. You need also monitoring the CPU when the service is stoping. I suspect that in this moment the CPU is at high level and maybe the memory also. And that can cause the timeout, then the stop of that service. You can set recovery action restart service for a while.

Dan,

I did what you said which stopped the service from failing. I also looked into what could be causing the high memory usage and discovered that someone had turned on active protection on Sophos Antivirus on the server. This seems to have stopped the error messages in the logs.

Many Thanks for your help.
