WSPSRV.exe memory leak

Hi All,

Recently we have found that one of our TMG servers is exhausting all memory on the server, paging its disk and eventually crashing. Further analysis has shown that the process using all of the server resource is WSPSRV.exe.

I've tried numerous trouble shooting steps including updating Nic Drivers, rolling our entire EMS array to service-pack2, running the BPA tool to no avail.

Does anyone have any idea what could be causing the memory leak on this process?

Regards,

Patrick S
