[Buildbot-devel] Defunct processes in buildslave after ShellCommand completion

[Mitch Oliver]

After a ShellCommand completes I frequently end up with defunct
processes in my process list, and the commands always end up with the
following exception in my buildmaster waterfall:
  command timed out: 1200 seconds without output, killing pid [pid]
  SIGKILL failed to kill process
  using fake rc=-1
  program finished with exit code -1

  remoteFailed: [Failure instance: Traceback from remote host --
Traceback (most recent call last):
  Failure: buildbot.slave.commands.TimeoutError: SIGKILL failed to kill process
  ]

This occurs using buildbot 0.7.4 in Python 2.3.3 with Twisted 2.4.0 on
Solaris 10 (Sparc).

Has anyone else run into this problem?  I saw a message in the
archives about something similar on NetBSD, but the thread seems to
have died.

Thanks,
Mitch Oliver
