>Description:

When running the tests in /usr/tests/fs/ffs on sparc, after the tests
have completed, there is one or more h_ffs_server process still
running in the background.  See for example the "ps-post-test" lines
near the end of

  http://releng.netbsd.org/b5reports/sparc/build/2013.06.12.17.13.05/test.log

This has been happening for some time.  According to the log files on
babylon5, it started with the following commits in September 2012:

  2012.09.30.21.26.57 bouyer src/tests/fs/ffs/h_quota2_tests.c 1.4
  2012.09.30.21.26.58 bouyer src/tests/fs/ffs/t_miscquota.sh 1.7

>How-To-Repeat:

To reproduce by hand:

  cd /usr/tests/fs/ffs
  atf-run
  ps -glaxw | grep ffs_server

 i still see this on real hardware.  it's much worse on SMP.

 there are often over 50 processes left at the of the run in
 tests/fs/ffs.

 Could you describe your hardware in more detail?

 Does further increasing the timeout in the test_case_root() function
 in ffs_common.sh fix the problem for you?

 SS20 with two SM70 (75mhz) cpus (i think that's right.)  384MB ram.

update.

 pretty sure this still fails, but my ss20 is running something that
 may or may not be with the latest atf, so i'm running a build and
 will see what happens.

i tried this, increasing the timeouts by 10x and it does not help.

 FWIW: I see very similar effects on my evbarm test runs
 (http://www.netbsd.org/~martin/evbarm-atf/), but not on the shark
 runs. My bet is on something MD in mutex/pthread land.
