Re: Mysterious ISA firewall /SQL lock-up and server slow-down

OK, an update...

Changing the ISA logging to text didn't change anything...

The culprit seems to be the WSUS "Update Services Auto approval" task. I
changed this task to run only at night, and the problem has gone away! I left
the server performance task alone as a hunch, and indeed, it didn't cause the
problem.

Now, my follow-up question is this...is it OK to only have this run at night
only? Any disadvantages I should be aware of? Any ideas to make this process
not take 100% CPU when it does run?

I wonder if I should go back to WSUS 2.0...I don't recall having the issue
then.

Thanks!

Hello,

Thank you for posting here.

According to your description, I understand that:

You receive the Event ID 14079 that indicates ISA service is unexpected
stopped every hour.

If I have misunderstood the problem, please don't hesitate to let me know.

Suggestions:
=======================
I suspect that this may be a sever performance issue. By default, the
Performance report will contain the ISA logs, RRAS logs, or Backup logs.
Performance data collection is triggered by a Task Scheduler task called
Collect Server Performance Data (%sbsprogramdir%/monitoring\mssbsssr.exe
-perf). It gathers server performance statistics, and then places that data
into the database. The scheduled task is configured to run every hour and
it is very CPU and disk intensive. On some machines with slow disks or slow
CPUs will result in the similar issue. To narrow down the issue, you can
manually change the task schedule to check how it works such as making it
run every 2 hours or only running at night when no-one is onsite.

For the further investigation, please help to answer the following
questions:

Information needed:
=======================
1. Will the users lose the Internet connectivity when you receive the Event
ID 14079?
2. If possible, how everything works if you disable the Collect Server
Performance Data task?


Generally speaking, performance issues are difficult to troubleshoot. To
troubleshoot the issue, we usually need to spend quite some time to perform
steps to find the problem causer due to complexity on technical side. If
this issue is urgent, we highly recommend you contact Microsoft Product
Support Services so that a dedicated support professional can resolve the
issue for you in the most efficient way. The Public Partner Newsgroup
Support is mainly for non-urgent break fix issues where a response within
24-hours is acceptable. I appreciate your understanding and cooperation
during the troubleshooting process.
