Hey gurus,

We've an ip440 with ipso 3.3 and 4.1 SP3.

Last Thursday night after adding a new firewall object and the associated rule, NAT, 
ARP and static info, I installed the policy and then rebooted the FW via the voyager 
interface (I've had probs b4 with arp settings not taking sometimes).

After the reboot performance had taken a big hit, especially file sharing and web 
serving. I reinstalled the prior policy with no effect. Performance  has degraded 
markedly.

The last policy change b4 this was 2 months earlier, and the FW has been rebooted a 
few times since then with no problem.

Then today while searching for the cause l found the following error message:

"Sep 23 14:09:52 fw1001 [LOG_CRIT] kernel: ex_expire: c6e58a58 (data: c6e58a2c) ld_del 
failed to ex_remove !"

Searching through the archives l see that this is caused by a bug in flows fixed by 
installing SP5.

Can anyone confirm if this is so? Could this be the cause of my sudden degraded 
performance?

Also l decided to do a fwstop/fwstart to see if this would clear some tables, and 
maybe improve the fw performance. The moment l did the fwstop, my ssh session froze. 
When l investigated the box l found it in the process of rebooting. Very disturbing.

Though performance did improve somewhat, the reboot was very disturbing. Has anyone 
else experienced this problem? Could the crash/reboot have been related to the 
performance issues?

Thanks for any help or advice.
