I had 4 system freezes (had to reset) in one day on two machines using the Red Hat 6.2 stock install. :-( Two were nfs-related I think - one machine hung during an nfs mount, then after resetting it, the other machine hung. The mouse tracked, but couldn't do anything else - CTRL-Alt-Backspace, or -Del, or CTRL-Alt-F1, etc. The other two crashes seemed to be running out of swap. When Linux runs out, it seems to not just kill the program that couldn't allocate memory, but sometimes lock up the whole system. Though a possibility is the swap partition type. (Both these crashes were on the older dual boot RH 4.2 / 6.2 system.) I haven't tried hammering the system again, so I don't know if this is a fix or not. Because I was bouncing between RH 4.2 and RH 6.2, I wanted to share the swap partition, so I did a swapoff/mkswap/swapon, choosing swap partition type v0 for backward compatability. Changing this to type v1, now that I've basically finished with RH4.2, seems to have improved things. Though, like I said, I haven't tried running the system out of VM since then. NB: ImageMagick leaks memory badly in RH 6.2. You can run out of swap. luke -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://slug.org.au/lists/listinfo/slug
