Description Mark Hlawatschek 2007-10-01 11:56:53 EDT
Description of problem:

A strace to the fenced pid causes fenced to stop

Version-Release number of selected component (if applicable):

fenced -V
fenced 2.0.70 (built Jul 13 2007 14:41:16)
Copyright (C) Red Hat, Inc.  2004  All rights reserved.

How reproducible:


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
Actual results:
fenced is not running any more

Expected results:
fenced should run in "traced" mode

Additional info:
Also a killall -SIGSTOP fenced; killall -SIGCONT fenced will stop the fenced.
