Crash dump failure

Boyo — Sun, 26 Feb 2006 19:56:40 GMT

Hello all,

I'm running hpux 11.00 on an rp7400 and I'm trying to do a crash dump, but when it gets to 73% done I'm seeing:
ERROR: can't get low memory buffer space for high memory page. Dump aborted
ERROR: write error on device 64:0xb. Dump aborted.

Can anyone help?

Cheers

Looks like a disk error on the dump lvol. Run a dd test to see if there are any bad spots on the dump volume:

dd if=/dev/vg00/rlvolXX of=/dev/null bs=128k

If there are multiple dump lvols, run the command on those too. And look in syslog.log to see if there are errors being reported already.

Hi Bill,

The dd reported no errors on the dump lvols and syslog is also not reporting any disk errors.

Hi,

Try to trace the issue with this command below :

# savecrash -rv

From here, you can see whether the problem due to the harddisk or the low memory swap or memory issue.

You can check also with /var/adm/tombstones file, /var/opt/resmon/log/event.log file, CSTM.

Hope this information can help you.

Cheers,
AW

Shalom Boyo,

Have you recently increased memory and not increased the lvol for dump?

If there is no error, this is a possible cause.

The dump lvol must be half of system memory to work right.

I think I will need to increase the dump lvol as its currently 7GB, but the system memory is 32GB.
