Hello,

Have a TMGSP2RU3 running on 2008R2SP1 in a VM with dynamic memory on a Hyper-V 2008R2 server and no VMQ's.
After installing these updates TMG stops passing traffic after an unspecific amount of time, typically an hour or two.

Uninstalling these updates brings everything back to normal. This installation has worked flawlessly for years.

Any suggestion what update is causing this? Any recommended action?

This is a production environment and I have had no time to investigate yet.

Regards,

Henning

Hi

Thanks for your post here.

is there any error information on TMG  when the issue occurs?

We really need some detailed information.

Best Regards

Quan Gu

Does the Firewall Service crash? Does the TMG Server itself become unresponsive? Can you still RDP to the TMG Server once it is "in state"?

Tell us more about your environment. How many clients are going through TMG? Is it forward proxy, reverse proxy, both?

It could be possible that there is a memory leak or you are experiencing port exhaustion. There are no known issues that I am aware of concerning a windows hotfix. You may want to gather some Perfmon Data specifically around the TMG related counters to see how long this takes and if there is a trend.
