Created attachment 179629 [details] /var/log/messages I using FreeBSD 11 as BRAS with mpd5-5.8 on VMWare ESXi 6.0.0 (3620759) and system crash and reboots abouts every three days. What can be wrong? $ freebsd-version -uk 11.0-RELEASE-p2 11.0-RELEASE-p7 Feb 5 02:29:36 BRAS3 kernel: current process = 12 (irq275: vmx2) Feb 5 02:29:36 BRAS3 kernel: trap number = 12 Feb 5 02:29:36 BRAS3 kernel: panic: page fault Feb 5 02:29:36 BRAS3 kernel: cpuid = 2 vmx2 used for PPPoE customers connected via mpd5 Server: HP Proliant DL380 G7 with Intel Xeon E5630 and Broadcom NC382i GE In sysctl I change only this: kern.ipc.maxsockbuf=23175936 Attaching /var/log/messages about this reboot. Another virtual instanced of FreeBSD on this VMware working very well and not reboots.
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.
