Hello,

We're running ipfilter 3.4.28 on most of our Solaris boxes (around 30 
machines in total). Generally it works very well, but we have seen a 
couple of kernel panics in ipfilter code, the latest occuring this 
morning. The machine is one of our mail servers - it had been up for 
around 10 months and is running Solaris 8 Generic_108528-19. It wasn't 
under heavy load at the time (~4:25AM).

In looking back at the ipfilter mailing list I see a couple of similar 
problems but I couldn't find a resolution. I'd appreciate any thoughts 
on this one.

Thanks,

Rich
