But slowly, first read what happened at our site: !!! !!! !!! !!! The system crashed with an ACCVIO on the Kernel Stack. !!! !!! So, before you try it yourself, ask your System Manager. !!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If you should come up with any suggestions, comments or anything like that, please respond to me directly, because I'm not on the INFO-VAX mailing list. regards - Ralf Bayer ** Computing Center at the Technical University of Darmstadt ** ** Federal Republic of Germany ( West Germany ) ** #d22%ddathd21.bitnet@wiscvm.wisc.EDU (from ARPAnet) #d22@ddathd21 (from BITNET / EARN) (Beware of the number sign - it's part of my User-ID)
