Tried setting maxusers to 256 in kernel. Still crashes
with 4 GB RAM installed when load occurs, like 'make
-j 16 buildworld'.

Compiled a debug-kernel, but after a crash it says
"savecore: no dumps found".

Kernel has:

makeoptions    DEBUG=-g
options         KDB
options         KDB_TRACE
options         KDB_UNATTENDED
options         DDB
options         DDB_NUMSYM
options         GDB



Swap-area is 8 GB.

Disabling the onboard Intel ICH5 UDMA100 controller
make the server boot go into mulituser.

Running with DEBUG=-g seems to make the server crash
less frequently.

kern.sync_on_panic is unchanged (=0).

Am I compiling wrong settings into the kernel, since I
don't get a dump?
