i have ported  the snort code for own purposes and now upgrading and
modifying that will take a lot of
time and effort..
Does any one encountered the similar situations where in  a user is trying
to do a http POST and
snort is trying to delete TCP LWsession and crash in  TcpSessionCleanup.


Thanks,
Prithvi
