next-20080808: bash: fork: Resource temporarily unavailable

Hi.

Beginning with next-20080808 after letting the system run for 5 minutes
or so, I get an error from the fork call, e.g.:

"bash: fork: Resource temporarily unavailable"

Doing an "echo c > /proc/sysrq-trigger" I was able to get an vmcore dump
of the running kernel using the kdump mechanism.

what should i do next?

with kind regards
thomas
