Del Vecchio) Newsgroups: comp.sys.sgi Subject: 3130 Problems Message-ID: Date: 13 Dec 90 21:42:05 GMT Organization: Carnegie Mellon, Pittsburgh, PA Lines: 27 Sorry to bother all of you 4D-type people, but... We have been having problems with a few 3130s that we have at a high school. I have net access (through this account) and have been porting a variety of software to the machines. Unfortunately, I have been able to crash the machine fairly easily. If I run any program which is too large, it seems, the machine hangs. It has happened to me compiling, with a compression program called "sqz", and is most easily demonstrated with emacs, by simply looking at a large file (several megs), which will work file, and then deleting a line, for example. The machine will go into a dead state. It will respond to pings and the terminal drivers will still work (you can watch control characters echo), but it is dead. It is also worth noting that editing the same file which causes the crash on either of two 4 meg machines works on an 8 meg, but larger files will also cause the 8 meg to crash. It is possible that we haven't noticed these problems before because we didn't run anything large enough; the only other possibility is the shell that I ported (tcsh, using BSD4.4 sources to csh). I had to make some strange modifications to the signal handling code to get it to work. I believe we are running OS version 3.6. Does anyone know what this is, or, more importantly, how to stop it from happening? Thanks for any info. -Vincent Del Vecchio (vd09@andrew.cmu.edu)
