The machine had no hardware failures running 6.x...6.4 in the last 3 years running about 20..25 Jails. Therefore I don't think it is a hardware error. The crash happened during someone recompiling most of his packages in jail while running cvsup on /usr/ports in another jail. So there was pretty much I/O and CPU usage. After crash the geom_mirror was degraded on ad4 (ad6 working). I guess a) the vmcore was successfully written to the SWAP b) geom_mirror is unstable under heavy load, maybe it's the origin of the crash. swap resides on that geom_mirror, too. I'm not yet able to get some useful information out of the 230MB vmcore.0 Maybe I may provide useful information about the crash if someone can tell me about how to get theese from vmcore.0. info.0 says: Dump header from device /dev/label/TOPSWAP Architecture: i386 Architecture Version: 2 Dump Length: 246185984B (234 MB) Blocksize: 512 Dumptime: Sat Mar 14 22:43:46 2009 Hostname: top.uugrn.org Magic: FreeBSD Kernel Dump Version String: FreeBSD 7.1-STABLE #0: Sat Mar 14 20:06:04 CET 2009 r...@top.uugrn.org:/usr/obj/usr/src_RELENG_7/sys/TOP Panic String: vm_page_insert: page already inserted Dump Parity: 31664128 Bounds: 0 Dump Status: good Regards Raphael Becker -- Raphael Beckerhttp://rabe.uugrn.org/ GnuPG:E7B2 1D66 3AF2 EDC7 9828 6D7A 9CDA 3E7B 10CA 9F2D .|.|.|.|.|.|.|.. pgpeqlW0RKPEi.pgp Description: PGP signature

GCC build causes panic: page already inserted
I saw that someone else had this happen last week... It is not a hardware failure. While building the latest GCC 4.4 from /usr/ports/lang/gcc44 I got a core dump with the message vm_page_insert: page already inserted I build this port every week on a Toshiba laptop (1.8GHz Core 2 Duo, 1 GB RAM, 160 GB HD, plenty of free space, RELENG_7).
