Hi,
Background:
2 x TMG Servers 2010 with latest hotfixes and rollups installed on fully patched 2008 R2 OS
both TMG servers are configured with dual NIC's - one internal one external and both nics are configured in an NLB through TMG
Client OS is mix of Windows 7 and Windows 8 with browsers being from IE8 to IE10.
Issue:
We are getting random 502 errors with the error saying Error Code: 502 Proxy Error. The requested resource is in use. (170).
This happens to all users randomly - they could be accessing any site. Hitting refresh on the browser resolves the issue.
It always seems to specify the same TMG server. But one thing I have noticed is on the 502 error page it shows the incorrect time - it's exactly 1 hour out. Yet the time on both TMG servers in the OS is identical.
Thanks in advance.
