It might be shortage of memory or shortage of some table space. (unlikely since you increased maxusers by 10) bsd/os 2.0 had a vm flaw that could consume memory under certain conditions. According to bsdi this is fixed in 2.1. It might also be "zombies" piling up consuming system resources. In short: find out what is consuming which resources,then a fix is likely to be found. O'reilly has a nice book "system performance tuning" where a lot of this info can be learned. kornel (kornel@netjet.com) wrote: : Hi, : I was wondering if anyone ran into the problem that our shop has : been struggling with for a while: : We get a 'can't fork new process: Temporarily out of resources' error : from the netscape server on a BSDi box.
