Comment 4 for bug 1367956

In my case the PIDFILE is created, but it is empty. bash -x output is below for a start.
I only see this behaviour on one arbiter. On other that I have, it works always.
If I put in a sleep for 1 second for example, before the pid is gathered and written to the pid file, it works also always on this problematic node.

garb version is Percona-XtraDB-Cluster-garbd-2-2.11-1.2675.rhel6.x86_64
