Hi,
During heavy shm swap tests I get the following error messages and the
machine locks up:
This happens at least with 2.3.39 up to 2.3.40-pre4 with SMP
enabled. I think I did see it in earlier versions also. On UP it seems
to work fine. The testrun was done with HIGHMEM=64GB and 8GB RAM but
the error also happens with highmem disabled.
Greetings
Christoph
