Hi cygwin team :)
I have found something what may be a cygwin bug. 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:

It looks like the cons_master_thread already exited, maybe clearing the master_thread_started

Thanks for your reply.
Yes, sure, will test it with 3.5.3 as well. Due to round trip times
with the client this may take one or 2 weeks, however.
Just wanted to ask if the 3.4 branch is end of life?
Best regards,

Thanks in advance.

3.4 branch: no more bug fix nor release.
3.5 branch: bug fix releases only.
3.6 branch: will be released with new features.

It looks like the master_thread already exited while thread 1 is waiting for some event

Sometimes a Cygwin strace can be helpful, for example:
$ strace -o drbdadm.strace drbdadm <ARGS>
or equivalent however you execute the program.
Attach the strace output as text if possible, otherwise if too big, xz, bz2, lz,
zstd, gz.

Line 1914 of fhandler/console.cc is:
WaitForSingleObject (thread_sync_event, INFINITE);
This waits termination of cons_master_thread(). However, it does not seem
that the cons_master_thread exists in thread list obove. If the thread was
terminated normally, thread_sync_event should has been set.
