BigSuds - bigsuds.ConnectionError: BadStatusLine: ''

Also, for what it's worth, I see it thrown by both bigsuds and httplib:

httplib:

httplib.BadStatusLine 

This particular exception is getting thrown right after creating the connection handle to the load balancer via bigsuds.

try:
    logging.info("Connecting to BIG-IP and pulling statistics...")
    b = bigsuds.BIGIP(hostname=ltm_host, username=user, password=password)
    logging.info("Requesting session...")
    b = b.with_session_id()
except bigsuds.Connecti , detail:
    logging.critical("Unable to connect to BIG-IP. Details: %s" % pformat(detail))
    sys.exit(1)

You can see I am catching bigsuds.Connecti but I guess I should also catch httplib.Connecti also and retry.

bigsuds:

Traceback (most recent call last):

raise Connecti ('BadStatusLine: %s' % e) 
bigsuds.Connecti : BadStatusLine: 

So in this exception, it is actually being caught by bigsuds and rethrown as a wrapped exception. It is interesting to note that the place where this crashes -- get_tcp_statistics() -- is pretty deep into the metric gathering.
