The NeXT I was using filled up its local disk (swap file grew while running Mathematica). Eventually the machine totally wedged and I had to power cycle it. Now when it boots it gets stuck trying to handle a page fault. There doesn't appear to be any way of doing file management from the monitor / debugger - or am I missing something? (Otherwise I would have tried emoving files.) Any ideas on how to fix this? Another complication: it's running afs and the problem comes up just after AFS loads. Is this the right group for this question - if not, where should I ask? -- Philip Machanick philip@pescadero.stanford.edu

When the machine came back up, I found that my dock parameters (preferences) had been wiped! It seems that this was all the damage that was done, yet, there must be something poorly designed in the interaction between mathematica and the NeXT Step memory manager which allows mathematica to grab sections of the hard disk which are already in use, for the purpose of virtual memory allocation. ---- Brad

I had lots of replies on this - the best summary is: -- From: matthews@ectds.com To: philip@pescadero.stanford.edu Subject: Re: swapfile death - help from the ROM monitor, bsd -sb (-s single user, -b don't read /etc/rc.boot) mount -o remount / # so you can write to it dig out where the problem really is. If it's only the swapfile, rm /private/vm/swapfile; touch /private/vm/swapfile; chmod 1600 /private/vm/swapfile # removing it now won't do any harm, it isn't being used might wanna fsck /dev/rsd0a while you're there halt reboot. -- Thanks to everyone else who responded. -- Philip Machanick philip@pescadero.stanford.edu
