It has only happened maybe 6 times over several years.  This is on Windows 10 64-bit with cygwin 3.1.4 x86-64. No idea how to reproduce.  Workaround or other tips appreciated.  It hangs forever (or at least for a few hours) and must be killed (Ctrl+C in shell doesn't work). I've attached a redacted cygcheck output.   Here are the stacks of the 3 threads within the date.exe process while it is hung: Thread 1: ntoskrnl.exe!KiSwapContext+0x76 ntoskrnl.exe!KiSwapThread+0xbfd ntoskrnl.exe!KiCommitThreadWait+0x144 ntoskrnl.exe!KeWaitForSingleObject+0x255 ntoskrnl.exe!KiSchedulerApc+0x397 ntoskrnl.exe!KiDeliverApc+0x2e8 ntoskrnl.exe!KiSwapThread+0xc98 ntoskrnl.exe!KiCommitThreadWait+0x144 ntoskrnl.exe!KeWaitForSingleObject+0x255 ntoskrnl.exe!NtWaitForSingleObject+0x10b ntoskrnl.exe!KiSystemServiceCopyEnd+0x28 ntdll.dll!NtWaitForSingleObject+0x14 KERNELBASE.dll!WaitForSingleObjectEx+0x93 cygwin1.dll!feinitialise+0x1df98 cygwin1.dll!feinitialise+0x1e050 cygwin1.dll!feinitialise+0x4edb cygwin1.dll!strtosigno+0x513a cygwin1.dll!_main+0x253 cygwin1.dll!secure_getenv+0x44e6 cygwin1.dll!setcontext+0x59d cygwin1.dll!sigfillset+0x35c7 cygwin1.dll!secure_getenv+0x488d ntdll.dll!RtlpExecuteHandlerForException+0xf ntdll.dll!RtlDispatchException+0x219 ntdll.dll!KiUserExceptionDispatch+0x2e cygwin1.dll!dlerror+0x820 cygwin1.dll!dlerror+0x1101 cygwin1.dll!dlerror+0x113d cygwin1.dll!cygwin_dll_init+0x4ae cygwin1.dll!setprogname+0x3d53 cygwin1.dll!setprogname+0x3e04 Thread 2: ntoskrnl.exe!KiSwapContext+0x76 ntoskrnl.exe!KiSwapThread+0xbfd ntoskrnl.exe!KiCommitThreadWait+0x144 ntoskrnl.exe!KeWaitForSingleObject+0x255 ntoskrnl.exe!KiSchedulerApc+0x397 ntoskrnl.exe!KiDeliverApc+0x2e8 ntoskrnl.exe!KiSwapThread+0xc98 ntoskrnl.exe!KiCommitThreadWait+0x144 ntoskrnl.exe!KeWaitForSingleObject+0x255 ntoskrnl.exe!NtWaitForSingleObject+0x10b ntoskrnl.exe!KiSystemServiceCopyEnd+0x28 ntdll.dll!NtWaitForSingleObject+0x14 KERNELBASE.dll!WaitForSingleObjectEx+0x93 cygwin1.dll!strtosigno+0x4b7 cygwin1.dll!secure_getenv+0x4410 cygwin1.dll!setcontext+0x59d cygwin1.dll!sigfillset+0x35c7 cygwin1.dll!secure_getenv+0x488d ntdll.dll!RtlpExecuteHandlerForException+0xf ntdll.dll!RtlDispatchException+0x219 ntdll.dll!KiUserExceptionDispatch+0x2e cygwin1.dll!setprogname+0x1293 cygwin1.dll!setprogname+0x1e9a cygwin1.dll!alloca+0x169ee cygwin1.dll!dlfork+0x110c cygwin1.dll!dlfork+0x223a cygwin1.dll!feinitialise+0x1c9cf cygwin1.dll!feinitialise+0x1da54 cygwin1.dll!setprogname+0x3d53 cygwin1.dll!setprogname+0x3e04 KERNEL32.DLL!BaseThreadInitThunk+0x14 ntdll.dll!RtlUserThreadStart+0x21 Thread 3: ntoskrnl.exe!KiSwapContext+0x76 ntoskrnl.exe!KiSwapThread+0xbfd ntoskrnl.exe!KiCommitThreadWait+0x144 ntoskrnl.exe!KeWaitForSingleObject+0x255 ntoskrnl.exe!IopSynchronousServiceTail+0x24a ntoskrnl.exe!NtReadFile+0x59f ntoskrnl.exe!KiSystemServiceCopyEnd+0x28 ntdll.dll!NtReadFile+0x14 KERNELBASE.dll!ReadFile+0x77 cygwin1.dll!sigfillset+0x29e1 cygwin1.dll!setprogname+0x2d63 cygwin1.dll!setprogname+0x3326 cygwin1.dll!setprogname+0x3d53 cygwin1.dll!setprogname+0x3e04 KERNEL32.DLL!BaseThreadInitThunk+0x14 ntdll.dll!RtlUserThreadStart+0x21 Thanks -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
