Description of problem: https://build.gluster.org/job/centos6-regression/4502/ is one of the few occurrences where slave24 is misbehaving. After running ~2 hours the regression tests fail without providing a log. This slave has now been disabled through https://build.gluster.org/computer/slave24.cloud.gluster.org/ to prevent further annoyance.
I don't see any evidence of the lack of logs. It seems to have had a connection issue. Restarted the machine and it's now back in the pool.
