My 7.2 FreeBSD server has started to crash with kernel trap 12. I googled
around and most of the topics I found were about faulty RAM or other harware
problems. This is VMware vitual machine so I see no way of hardware problems
as we even tried to move the machine around VMware nodes to see it's RAM. It
worked absolutely fine for about two months, but now sometimes the server
lives for up to 5 hours, sometimes it panics in 10 minutes. Is there anyone
that can help me to resolve the problem?
Here are few errors on crash:
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
cpuid = 2; apic id = 02
fault virtual address = 0x10
fault code = supervisor read, page not present
