Good point, I didn't think about this, but once i started getting over 1000 of these and it just kept growing, I started to rule it out, but I won't this time. I've moved the server over to 7.0 now which is taking load. I'm already thinking this problem is NOT fixed and is the same behavior as in 4.x because I'm seeing quite a few FIN_WAIT_1's collect now. [mirror0:~] netstat -an | grep FIN_WAIT_1 | wc -l I set the keepalive lower as I've mentioned, 15 mins and 30 sec intervals... I'll see if I have any specifically that stick around for a while and I'll try dumping one of those sessions and see.... -- Robert Blayzor, BOFH INOC, LLC rblayzor@inoc.net http://www.inoc.net/~rblayzor/
