Hello,

My application was working fine in last month, but its getting hanged indefinitely after the system update.

Application is getting hanged while calling the couninitialize:

Call stack of the hang:

ntdll!NtDelayExecution+c

KERNELBASE!SleepEx

KERNELBASE!Sleep

rpcrt4!RPC_SERVER::UnregisterIf

rpcrt4!RpcServerUnregisterIf

combase!CRIFTable::UnregisterServerInterface

combase!CRIFTable::CleanupRIFEntry

combase!CHashTable::Cleanup

combase!CRIFTable::Cleanup

combase!ChannelProcessUninitialize

combase!ProcessUninitialize

combase!DecrementProcessInitializeCount

combase!wCoUninitialize

combase!CoUninitialize

Asper the Debug diag report, Detected possible blocking or leaked critical section at combase!gChannelInitLock+14 owned by thread 0

mpact of this lock

25% of threads blocked

(Threads 3)

The following functions are trying to enter this critical section
combase!CROIDTable::ClientBulkUpdateOIDWithPingServer+352

And the thread 0 call stack:

ntdll!__RtlUserThreadStart+2f	  
ntdll!_RtlUserThreadStart+1b

Can you suggest why the application is getting hanged while calling the combase!CoUninitialize and how to resolve this.
