There is/are 1 thread(s) in total in the server that may be hung. 

Any idea what could be up here?

Thanks Damien

It sounds to me like your LDAP server is not responding in a timely manor. The fact that you have a hung thread rather than a network error indicates to me that you are successfully communicating to LDAP. If you are attaching this to the Active Directory backed LDAP, it could be overtaxed. We have used ADAM servers in the past to get around slow LDAP response time. However our responce times were around 3-5 seconds instead of 12+ minutes. This could also be a deadlock. I have seen hung threads as a result of implementing XD extensions where the nodes deadlocked their communication (But these were not WebContainer threads). To fix this issue, we ditched XD extensions in favor of a NetScaler setup.
