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 rc.conf: dumpdir="/var/crash" dumpdev="/dev/amrd0s1b" 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? Claus
