etcd returns 500 internal server error on ubuntu which causes postgres to crash.

Hi,
Postgres server crashes as a node tries to write a value in etcd and gets 500.

self.put_client_path("/members/%s" % member, {"value": connection_string, "ttl": self.ttl})

File "/home/i074560/shashank/governor/helpers/etcd.py", line 40, in put_client_path
opener.open(request)
File "/usr/lib/python2.7/urllib2.py", line 406, in open
response = meth(req, response)
File "/usr/lib/python2.7/urllib2.py", line 519, in http_response
'http', request, response, code, msg, hdrs)

What is the impact if we just catch this exception and retry for few times instead of just letting postgres crash on first attempt?
