I added: dumpdev="AUTO" to: rc.conf Rebooted the system and tried to get it to crash again... And indeed it does in process 9: taskq Then it starts dumping which takes a couple of seconds as the machine has 2 GB Ram... Than it reboots... and the next thing you know... savecore does NOT recognize a dump on the swap file system. If does not save anything to /var/crash... Tried this about 10 times... No luck... Any other idea's? Thanks! Jan
