Sometimes (1 out of 1000 times) a drbdadm.exe process (which is part of WinDRBD's user mode programs originally written for Linux) hangs for several days on exiting (closing the console). I got a minidump and analyzed the dump with gdb (the minidump enabled version at https://github.com/ssbssa/gdb) I have to note that the application (drbdadm.exe) is run from a Windows Service. Furthermore it is not a full cygwin installation however the cygwin1.dll (3.4.10-1) is in the $PATH. here is the gdb output: (gdb) info thread Id Target Id Frame * 1 Thread 0x14c8 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll 2 Thread 0x2e0 0x00007ffc6a405ee4 in ntdll!ZwReadFile () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll 3 Thread 0x1060 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll 4 Thread 0x858 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll 5 Thread 0xe40 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll (gdb) thread 1 [Switching to thread 1 (Thread 0x14c8)] #0 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll (gdb) bt #0 0x00007ffc6a405ea4 in ntdll!ZwWaitForSingleObject () from C:\src\dlls-syms\ntdll.dll\6502806A1cf000\ntdll.dll #1 0x00007ffc66826d1f in WaitForSingleObjectEx () from C:\src\dlls-syms\KERNELBASE.dll\6502815021e000\KERNELBASE.dll #2 0x00007ffc492ebb42 in fhandler_console::close (this=0x800007f20) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/fhandler/console.cc:1769 #3 0x00007ffc492dc365 in fhandler_base::close_with_arch (this=0x800007f20) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/fhandler/base.cc:1202 #4 0x00007ffc49353640 in init_cygheap::close_ctty (this=) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/mm/cygheap.cc:133 #5 0x00007ffc492aee9f in close_all_files (norelease=norelease AT entry=false) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/syscalls.cc:81 #6 0x00007ffc49226763 in do_exit (status=0) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/dcrt0.cc:1125 #7 0x00007ffc4922693f in _exit (n=) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/dcrt0.cc:1240 #8 0x00007ffc49390899 in exit (code=0) at /usr/src/debug/cygwin-3.4.10-1/newlib/libc/stdlib/exit.c:65 #9 0x00007ffc49226923 in cygwin_exit (n=568) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/dcrt0.cc:1234 #10 0x00007ffc492280aa in dll_crt0_1 () at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/dcrt0.cc:999 #11 0x00007ffc49225c86 in _cygtls::call2 (this=0x7ffffce00, func=0x7ffc49226f80 , arg=0x0, buf=buf AT entry=0x7ffffcdf0) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/cygtls.cc:41 #12 0x00007ffc49225d34 in _cygtls::call (func=, arg=) at /usr/src/debug/cygwin-3.4.10-1/winsup/cygwin/cygtls.cc:28 #13 0x0000000000000000 in ??
