I'm trying to backup a DB on a large system (4 GB Mem, 4 CPUs). The DB cache
is set to 300.000 8k pages. (2,4 GB) When I try to start the backup
interactively I get the following error in the knldiag.err file:

12-18 00:19:02  8383 ERR 11000 d0_aopen Error during fork, resource limit.
12-18 00:19:03  8387 ERR 52012 SAVE     error occured, basis_err 3700

Does anyone have an idea which system imposed limit I'm touching here?

[root@aubir3db P01]# grep -v \# /etc/sysctl.conf | grep kernel
kernel.sysrq = 0
kernel.shmmax=3221225472
kernel.sem=4096 512000 1600 2048
kernel.msgmax=16384
kernel.shmall=3221225472

If I decrease the pages to 200.000 8k pages (1,6 GB) the backup is running
fine.

These happens on all 2.4 kernels and distributions I've tested (SLES and
Redhat, 2.4.7, 2.4.10-6, 2.4.16-enterprise, 2.4.17-preX). 

Just curious or am I missing something very basic (again)?

Thanx for any idea!

Merry Christmas!
