Hi,
I've been asked to help this former customer.
This box is running 5.2.1 with as most "exotic" application jave/tomcat. And it crashes too often. The first essential question for the customer is: Is this hardware??? So I did the 'make -j 8 buildworld' test, which it survived with flying colors.
What do I find in the logs:
Nov 12 11:22:01 ktc syslogd: kernel boot file is /boot/kernel/kernel
Nov 12 11:22:01 ktc kernel: panic: vm_fault: fault on nofault entry, addr: ee8fd000
Nov 12 11:22:01 ktc kernel:
Nov 12 11:22:01 ktc kernel: syncing disks, buffers remaining... panic: bremfree: removing a buffer not on a queue
Nov 12 11:22:01 ktc kernel: Uptime: 2d11h12m6s
Nov 12 11:22:01 ktc kernel: Shutting down ACPI

......
Nov 12 11:22:02 ktc kernel: WARNING: / was not properly dismounted
Nov 12 11:53:54 ktc syslogd: kernel boot file is /boot/kernel/kernel
Nov 12 11:53:54 ktc kernel: panic: vm_fault: fault on nofault entry, addr: ee79f000
Nov 12 11:53:54 ktc kernel:
Nov 12 11:53:54 ktc kernel: syncing disks, buffers remaining... panic: bremfree: removing a buffer not on a queue
Nov 12 11:53:54 ktc kernel: Uptime: 31m36s
Nov 12 11:53:54 ktc kernel: Shutting down ACPI
Now the panic in the syncing part, I can imagine to just be there since syncing disk after a panic has not really worked all that well in 5.x
Customer has disabled all warnings/witness/.....
And I can not make much of the comments on sys/vm/vm_fault.c:278, which is where the fault on nofault occurs...
My feeling says: upgrade to 5.3, but this being a production server running soem applications I know very little off holds me back.
So is this for sure a hardware problem, or just leftovers from 5.2.1????
