I have a wcf application that frequently hangs and the clients keep getting timed out.I did a windbg trace and it detected a deadlock. However, the deadlock seems to be in unmanaged code and i am not able to dig any further. Please help. Here is the WindDBG trace:

Of the 2 threads i understand the clrstack of one thread( which is stuck at managed code) but not the other. Here is the dumpstack for thread where i have no idea what is happening. It will be great if somebody could tell what this thread is doing.
