What version is the stable system? UFS or ZFS? Do both have 4G? What varies with the second system - software/settings?
The panic relates to a page fault, pointing to out of memory.
In general 4G for a system using ZFS is low. Keep an eye on ZFS ARC level, maybe set vfs.zfs.arc_max to keep some ram free for your software.
On my desktop I have seen excess "wired" allocations lead to problems. I get a wired reading using `top -d1 | grep Wired | awk '{print $6}'` Any chance you see over 3G wired?

We have a lot of such reports from netgraph users. (In reply to Shane from comment #1) yes, these systems have ZFS and above 4G of memory (4G BRAS, 20G another) I will try to add more then 4G of memory. # sysctl vfs.zfs.arc_max vfs.zfs.arc_max: 3046846464 # top -d1 | grep Wired | awk '{print $6}' 1168M Yes, when I added more memory than 4Gb - uptime looks well. |
