- Problem: you're sitting at a NeXT on a network, working
- away. Suddenly music starts playing and the system has a
- panic. This happens not once but many times. Sometimes
- locking up the system entirely so that even the power key
- is out of commission. This happens VERY often, like every
- ten minutes or so.
- Further info: there are a dozen nexts out there. Several
- people are working on them. When you switch box, it
- crashes on you again. Nobody else's box crashes. Well
- actually, one other person has a similar crash, once, but
- most are entirely unaffected. ps -aux shows only root and
- the user's processes running.
-
- This raises several possibilities, some paranoid, some more
- benign.
- (1) somebody is persecuting a particular user and causing
- her system to crash, perhaps by rlogging in and causing a
- system crash (but note that public sound and window server
- preferences are switched off) and nobody else seems to be
- logged in to these machines.
- (2) somebody is rlogging in and doing something that causes
- a system crash without realizing that they're doing this.
- But chances that they'd always log into a box used by the
- same person and never other people seem pretty low.
- (3) there's a bug somewhere in the OS or the user's
- filesystem is somehow corrupted. The only things running
- are edit and terminal. Also mail and VirtSpace, I guess.
-
- Any ideas?
