It has the internal identification `kern/1027'. The individual assigned to look at your bug is: freebsd-bugs. >Category: kern >Responsible: freebsd-bugs >Synopsis: panic on vm_map_insert >Arrival-Date: Wed Feb 14 11:30:01 PST 1996 ----- Hi... Realizing that I only submitted this on Wednesday, after I submitted it, I did one major change, just in case...I recompiled the kernel using gcc 2.6.3 (ya, I know, but 2.7.2 did work). Today, I finally got a chance to re-install that newer kernel, and the same thing happens. This code has been running okay on my 386 machine, but there is virtually no load on that machine, as it isn't being used for anything except to sit there and run right now, so nothing is really taxing the vm_space... The machine I'm trying to get it running on is used for everything, from news to httpd to postgres95 to...X sometimes (but with this new kernel yet). With the -stable kernel it has right now, she runs without a hitch, haven't had a panic in weeks which leads me to suspect the vm code vs a hardware problem (or else the new vm code is taxing a different part of the hardware then the old vm code?) I have swap spread over 4 drives right now: > pstat -s Device 1K-blocks Used Avail Capacity Type /dev/sd0b 102400 3492 98844 3% Interleaved /dev/sd1b 32768 3456 29248 11% Interleaved /dev/sd2b 32768 3456 29248 11% Interleaved /dev/sd3b 32768 3456 29248 11% Interleaved Total 200448 13860 186588 7% I'd like to get -current running on this machine, mainly because there are features in -current that I'd like to have, and because I found that -current was more stable on the 386, then stable was on the 486...and cause I like the idea of faster things like vm code and pipes :) Altho this machine is "live/production", I'm willing to test things out and try different things to resolve this problem, since most panics last me about 5 minutes, which I can easily account for (no users, just WWW traffic right now) Also, even though I have savecore turned on, I don't seem able to get a core file to diagnose. I'm including my config file at the bottom of this, just in case I'm missing *something* that I require to get a core file, but I've checked out LINT and GENERIC for any flags I think I'm missing, and...can't find any.
