Summary	0000009: The l7-filter application sometimes stops unexpectedly, blocking the NAT
Description	I have noticed that the l7-filter application, which categorises data for the protocol filter, sometimes isn't running. This causes all traffic, that the protocol filter would otherwise categorise and block if it matched any of the blocked protocols, to be blocked resulting in the NAT being completely locked down.
Additional Information	The web proxy still functions as the connections bound for the Internet originate from the server itself and are not from the internal side of the gateway. I solved the problem by having a script check that l7-filter is still running every minute and then restarting it, if it has stopped.
Tags	No tags attached.

Notes
(0000016) dsokoloski (developer) 2010-01-22 11:26	Based on several reports, it seems that under some circumstances (yet to be determined), the l7-filter server crashes. When this happens traffic forwarded to it for analysis goes no where - essentially blocking all further traffic. In the short-term, I will write a wrapper that logs this issue and restarts l7-filter on a fatal signal such as SIGSEGV.
(0000107) dsokoloski (developer) 2010-05-05 18:46	The issue has been resolved by James King whom supplied a patch. http://l7-filter.clearfoundation.com/tracker/view.php?id=3 [^]
