[Bug 1437742] Re: gnome-terminal never returns after heavy load btrfs operations (defragment, balance, etc.)

 

Could this be another manifestation of
https://bugzilla.gnome.org/show_bug.cgi?id=735101 ? It's another case of
gnome-terminal using 100% CPU, and unfortunately we're stuck and ran out
of ideas.

The next time it happens, could you connect to gnome-terminal with
strace (e.g. from an xterm) and see if it's stuck in a loop, like in
that bugreport?

How often can you reproduce this problem? (The main reason we can't
debug the upstream bug is that it happens once in every couple of
months, we can't force reproduce it.)

Title:
  gnome-terminal never returns after heavy load btrfs operations
  (defragment, balance, etc.)

Status in gnome-terminal package in Ubuntu:
  New

Bug description:
  Running `btrfs` commands which cause heavy system load (e.g. `btrfs
  filesystem defragment`, `btrfs balance`, etc.) in `gnome-terminal`
  causes the terminal never to return and use one CPU core at 100 %
  forever. There's no connection to the system load because interrupting
  that command (e.g. `btrfs filesystem defragment` with `SIGSTOP`) don't
  make `gnome-terminal` return, but keep hanging forever.
