Oh no, not this page allocation problems again. In summer I already posted 
problems with page allocation errors with 2.6.7, but to me it seemed that 
nobody cared. That time we got those problems every morning during the cron 
jobs and our main file server always completely crashed.
This time its our cluster master system and first happend after an uptime 
of 89 days, kernel is 2.6.9. Besides of those messages, the system still 
seems to run stable

I really beg for help here, so please please please help me solving this 
probem. What can I do to solve it?

First a (dumb) question, what does 'page allocation failure' really mean? 
Is it some out of memory case?


Thanks a lot in advance for any help,
 Bernd
