panic (cpu 0): vm_pg_free: page on o/h list

[Azim_3]

Hello All,

My sever got rebooted with the above mentioned error.
Server is compaq alpha ES40,O/S is TRU64 v5.1b with patchkit-4 is installed.
After browsing similar threads in the forum,the solution suggested was to install patchkit-5.
Can anybody pin point what could be actual problem.
Attaching the binary.errorlog, /var/adm/messeges
any help is appreciated

Kind regards
AZIM

Azim,

The binary.errlog is of no use for this case.
The actual problem is what you already copy/pasted in your attachement error_messages.txt .

You can check for yourself by examining the latest /var/adm/crash/crash-data.xx and look for the stack-trace:

panic
vm_pg_free
ubc_free_page
ubc_page_alloc
ubc_lookup
cfs_getapage
cfs_getpages
cfs_getpage
u_seg_fault
u_map_fault
vm_fault
trap
_XentMM

The fix is as described in your attachement, ie install ERP kit T64KIT0024519-V51BB25-E-20041218 on top of patchkit#4.

Alternatively you can install patchkit#5, where the same fix is already incorporated under the patchID OSF540-1274 which is part of pk#5 patchset 26010.00

Have Fun,
____ Johan.
