Description (partial)

Symptom:
You may observe the following application fault in the appliance's error logs:

Tue Sep  1 12:00:00 2015 Critical: An application fault occurred: ('client/graymail_config.py read_default_config|42', "<type 'exceptions.UnboundLocalError'>", "local variable 'fd' referenced before assignment", '[_coro.pyx coro._coro._wrap1 (coro/_coro.c:8500)|757] [client/graymail_config.py config_change|298] [client/graymail_config.py write_engine_config|62] [client/graymail_config.py read_default_config|42]')

This application fault is indicative of a problem with an internal configuration file on the appliance.  You may also encounter workqueue backups which occur as a result of the same underlying issue.

Conditions:
This application fault should only occur if Graymail is enabled.  Typically the missing configuration file issue that causes this application fault is caused by improper reboots of the appliance.
