I do not mind paying a visit to the machine, even if it costs me a day all in all. But I want to do it only once. Not 4 times. So I would like to find out from a distance _what_ to replace. I am asking too much. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

I cannot really (or easily) use this though, as the box is collocated, and not next door. If it would be here, I would long have tried replacing hardware parts to see what it is. I am now running memtest from ports. This gives no errors so far. But it seems only to test the unused RAM. I would have expected that the functioning of cache and RAM should be visible in some utility like systat.

Even though it's main purpose is testing RAM, it also shows the information about L1 and L2 cache. -- Toomas Aas | [EMAIL PROTECTED] | http://www.raad.tartu.ee/~toomas/ * Shell to DOS...
