[DRBD-user] drbd0: could not kmalloc() nbh

[Tim Tregubov]

Hiya -

Sorry if this has already been asked (I searched the lists and didn't 
find a resolution per say).

Is seeing lots and lots of this bad:
kernel:  drbd0: could not kmalloc() nbh
last message repeated 713 times
?

It was preceeded by a sync:
drbd0: Synchronisation started blks=15
drbd0: Synchronisation done.


I'm running: version: 0.6.12 (api:64/proto:62)
on:   2.4.21-15.ELsmp   (RH ES 3 Taroon Update 2)
compiled with: gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-34)
filesystem is ext3

At the time this happened I was running a 9.7GB untar onto the file 
system (shortly after the full sync).

The messages only appeared on one of the two systems.

Help!   I need to put this system into production monday morn, and I'm 
stressing. :-)

Thanks so much for any help!

Cheers,
Tim
