FreeBSD 4.2-STABLE (Jan 20) xscreensaver-gtk-3.26 installed as FreeBSD package. I'm not really so worried about seeing this fixed as I thought I should point it out to others. I have at least one production server that runs xscreensaver (to keep the local admin happy) and I wanted to let others know of the problem I found. When the webcollage screen hack runs it fairly regularly causes a full reboot - I haven't actually seen it happen yet, but here are the messages I seen in /var/log/messages: Feb 6 15:07:50 working /kernel: pid 2405 (ppmmerge), uid 1000: exited on signal 11 (core dumped) Feb 6 16:26:35 working /kernel: pid 3497 (ppmmerge), uid 1000: exited on signal 11 (core dumped) Feb 6 19:56:58 working /kernel: pid 4071 (ppmmerge), uid 1000: exited on signal 11 (core dumped) Feb 6 19:57:35 working /kernel: pid 4515 (ppmmerge), uid 1000: exited on signal 11 (core dumped) Feb 7 08:09:24 working /kernel: Copyright (c) 1992-2000 The FreeBSD Project. ... and the rest of the boot messages While the times seem to suggest that something was occurring in between (several hours in there ...) I can't find any other indicator of what could be causing it, and it doesn't happen when I disable the webcollage screen hack. Other occurances show varying times between the crash of ppmmerge and the reboot of the system (as short as 2 hours) but it's always the same thing ... ppmmerge coredumps and a few hours later the system reboots. I haven't caught it happening yet to watch what happens, nor have I been able to reproduce it by manually running webcollage in a root window. I suspect some sort of memory leak that eventually brings the system down, but I don't have details yet. So this is a) an early warning to others not to run the webcollage screen hack on critical systems, b) an invitation to others to research this further if they'd like. I'll probably take some more time over the next few weeks to try to isolate this better. I know this isn't much data, but I just thought I'd pass it on. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
