HTTP failure on University

Are there any other universities out there using SEF? We are experiencing almost daily http traffic stopping. The only resolution has been to reboot the firewall machine. Could it be http tunnelling software? Symantec hasn't been much help. ("Read your log files" and they don't show a problem) Would like to visit with any universities who have 6,000 to 10,000 users. Currently running 6.50 on NT, have also tried 6.52 on W2K with same results.
 
I work at a bank and we run ver 7.0. This also happens to us. We run it on a win2000 box. I have just one question. In your rules do you have *all turned on?
 
It takes a little more information than you've posted here.
Check out do a search on the archives for httpd stopping. Look at cpu usage/port usage, any messages in logs relating to kernel memory, port already in use etc
 
We have had a problem with our SEF 6.5.x regarding the number of ports used on the FW.
TCP/IP default is basicly to use any ports from 1024 or up, but by default I think windows has a max around 5000 so the problem you have could be that you run out of portnumbers for your http traffic.
There is a document that tells how to change this. It's done by using regedt32 (or regedit) but I don't remember the setting
If your installation is big also remember to kill inactive tcp/ip connections after some time because you could end up with the same type of problem anyway. The port problem is common in all big installation if they only have one fw to the internet regardless of product. I have seen this on Checkpoint too.
