The same behavior. > It may be worth peeking through /etc/rc.d/dumpon and imitating > some of the commands there to see if you can reproduce it. /etc/rc.d/dumpon creates symbolic link /dev/dumpdev. It's present in my /dev directory. I think a problem is somewhere deeply, probably with savecore(8). When a panic occurs I see in console process of dumping (size of RAM, number of pages, dump device etc.) and it's completely normal. -- Kind Regards, Alexander Shikoff minotaur@crete.org.ua Mob.: +380 67 946 31 49
