CVD communication service unresponsive
Article ID: CVD0005 Attempts to push updates to client fail.
CVD Process is running on client but push updates and readiness checks fail.
CVD uses OpenSSL which calls RAND_poll which calls Heap32First/Heap32Next. A deadlock situation can occur when Heap32First function and RtlAllocateHeap function are called by two threads at the same time. Affected platforms are windows 7 and 2008 R2.
Restart CVD process. To prevent future deadlocks, Microsoft hotfix described here may help.
