Greetings,

So Continuing on the path of diagnosing what's going on here
I monitored the memory consumption of the backup at issue.
It was hovering around 2.6g or ram.  About 4 hours later it
failed. 2.5g seems big to me.  I've read in the archives
that there's extra overhead because the backuppc dump
process forks and doubles the memory consumption.  In the
state the system was in last night, it'd have to get to
about 3.1g to exhaust the memory on the system.

So I've got a few questions?

Is this rate of consumption normal?

If so, about how much ram should I plan on having for a
backup of a system that has 10M files?

If no for question 1, what could be the culprit?  Perhaps a
memory leak in Perl or one of the underlying libraries?

Thanks again for any input you might have.

Andy
