Error description
When an integration server is configured for callable flows or secure connectivity (for IBM Integration Bus on Cloud), that integration server may hang forever on shutdown on certain versions of Windows. If this happens, then the integration server will log a BIP2204I message to the event viewer stating that it has stopped, but the integration node will later report a BIP2804E indicating that it has not shut down. The problem has been seen on Windows 7, but not later versions of Windows. On Windows 7, inspection of the hung DataFlowEngine.exe process using a tool such as Process Explorer shows the following stack: ntoskrnl.exe!KeWaitForMultipleObjects+0xc0a ntoskrnl.exe!KeAcquireSpinLockAtDpcLevel+0x712 ntoskrnl.exe!KeWaitForMutexObject+0x19f ntoskrnl.exe!PoStartNextPowerIrp+0xbb4 ntoskrnl.exe!PoStartNextPowerIrp+0x185d ntoskrnl.exe!KeAcquireSpinLockAtDpcLevel+0x91d ntoskrnl.exe!KeWaitForMutexObject+0x19f ntoskrnl.exe!ExQueryAttributeInformation+0x73a ntoskrnl.exe!KeSynchronizeExecution+0x3a23 ntdll.dll!ZwReleaseKeyedEvent+0xa ntdll.dll!EtwEventSetInformation+0x3f40 CommonServices.dll!ImbThreadPoolExecutor::?ImbThreadPoolExecutor +0x6b CommonServices.dll!stl_debug_terminate+0x47b8a CommonServices.dll!stl_debug_terminate+0x694 CommonServices.dll!stl_debug_terminate+0x916 ntdll.dll!LdrShutdownProcess+0x1d1 ntdll.dll!RtlExitUserProcess+0x90 mscoreei.dll!ND_WU1+0x18a mscoree.dll!CorExitProcess+0x10d MSVCR120.dll!_setusermatherr+0x2ab MSVCR120.dll!initterm_e+0x212 DataFlowEngine.exe!ImbMain::operator=+0x2a02 kernel32.dll!BaseThreadInitThunk+0xd ntdll.dll!RtlUserThreadStart+0x21 The process can be killed by using the Task Manager or a tool such as Process Explorer.
