[fuse-devel] when fuse process freeze, "ps ax" freeze , and gdb is not responding ...

[Alain S. <asp...@gm...>]

Hi

My fuse file system stop responding.

Doing a ps ax freeze the console.

I can get the pid of the fuse process using

grep ddumbfs /proc/[0-9]*/stat

But then starting
gdb  ddumbfs -p <pid>
freeze too

Finally I do a umount -f
and all freezed consoles come back to live and gdb give me an "inactive" process
where all threads are waiting for new request.s
I think the faulty thread get the time to finish when doing the umount
and when gdb get the control I see a thread waiting for new request.

Any idea to force gdb to take the control ?

strace freeze too.

And starting the process inside gdb, make gdb not responding to CTRL-C
when the process freeze.

This make me thing to a stalled NFS mount, doing a ls in such a
directory freeze the ls too, about the same way.

Any idea ?

Regards.
