BUG: unable to handle kernel NULL pointer dereference at 00000028

[julowe]

Hi all,
We recently upgraded to Zeroshell 3.9.0 on our APU2C4.

The load has been jumping up in increments of 50% and the system slows down around 100% or 150%.

The following errors precede the jump in load.

We have the nmap package installed and enabled, and the SQUID package installed, but disabled. No other packages.

Let me know what other information will help track this down.

Thanks,
Justin
