tracing fenced kills the process
Last modified: 2009-04-16 18:59:28 EDT
Description of problem:
A strace to the fenced pid causes fenced to stop
Version-Release number of selected component (if applicable):
fenced 2.0.70 (built Jul 13 2007 14:41:16)
Copyright (C) Red Hat, Inc. 2004 All rights reserved.
Steps to Reproduce:
1. get pid of fenced
# ps ax | grep fenced
9453 ? Ss 0:00 fenced -c
2. strace the pid
strace -p 9453
Process 9453 attached - interrupt to quit
close(7) = 0
close(5) = 0
close(6) = 0
exit_group(-1) = ?
Process 9453 detached
fenced is not running any more
fenced should run in "traced" mode
Also a killall -SIGSTOP fenced; killall -SIGCONT fenced will stop the fenced.
Fix now in CVS.
