TCP sessions hanging in FIN_WAIT_1?

Mon Apr 2 15:11:41 UTC 2007

Generic kernel, I had some stuff in there related to the http accept  
filter but I removed all that when I noticed the problem.  I moved  
the traffic over to if_em for testing and the problem went away, when  
I brought it back to mxge the FIN_WAIT_1 issue came back.  This was  
without rebooting or changing anything other than the interface.
