And my Gearman reports this error sometimes.

2015-07-25 10:50:44,914 ERROR gear.Server: Exception in poll loop:
Traceback (most recent call last):
   File "/usr/local/lib/python2.7/dist-packages/gear/__init__.py", line 
2614, in _doPollLoop
     self._pollLoop()
   File "/usr/local/lib/python2.7/dist-packages/gear/__init__.py", line 
2626, in _pollLoop
     ret = self.poll.poll()
IOError: [Errno 4] Interrupted system call

Not sure if it has anything to do with this problem.

In Jenkins GUI, Gearman connection is tested successfully on 127.0.0.1:4730.

Thanks.
