oopses with the following message:

Maschine's hardware:
Dual PIII 550 MHz
DPT I2O RAID
512 MB RAM
2 x 9,1 GB HD and 512 MB swap
Running RH 6.1 and adabas 11
It does NOT occur when kernel is not compliled for SMP and is also does NOT occur when we put more RAM into this maschine. But after all memory is used it happens again. So as long as no swap is needed and kernel is compliled only for one CPU everything works fine.
It does not seem to be a hardware problem, because a totally different maschine shows the same result.
We testet serveral preferences up to kernel 2.2.15-pre18.
Anyone an idea ?
