Krishna,
I hope this bug is fixed. If it is, can you close this bug?

While leaving my servers over the weekend, with a rsync from hdd to glusterfs (to keep them uptodate) the glusterfs process died regually.

A core dump shows the following backtrace:
Core was generated by `[glusterfs] '.
Program terminated with signal 11, Segmentation fault.

The glusterfs.log file shows:

The brick given (hoggle-raw) has been functioning correctly over the weekend and should never have been out of contact. (in fact its doing it now, even though the glusterfsd process is showing as running and traffic is being seen)

Unfortantly I am unable to determine what is causing the crash, as its done via an hourly cron job, but it should only be doing rsyncs between two data sources. (HDD => glusterfs)
