Yes. By now, if any dump was ever written to your swap partition, it will most probably have been overwritten by your heavy postgres activity. :) In RELENG_6, the dump device is chosen automagically during boot by /etc/rc.d/dumpon, but this is (alas) not the case in RELENG_5_x, so you'll have to manually specify it in /etc/rc.conf, i.e: dumpdev=3D/dev/ad0s1b Then make sure you have enough space in /var/crash, and try to reproduce your panic... Also, I think I read somewhere that there used to be problems with dumping and 3Ware RAID cards (you seem to be using one according to your kernel config, but you apparently didn't post a dmesg). However, it looks like revision 1.22.2.1 of src/sys/dev/twe/twe.c fixed that: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/twe/twe.c?rev=3D1.22.2.1&= content-type=3Dtext/x-cvsweb-markup Just to be sure, can you check if you got this version of twe.c, or 1.22.2.2 (which seems to be the RELENG_5_4 version, and thus it should be fixed). ------------D515224B21B865FA Content-Type: application/pgp-signature -----BEGIN PGP MESSAGE----- Version: GnuPG v1.4.1 (MingW32) iD8DBQFDF3AKsF6jCi4glqMRAvehAKC3nZZuUOEsE2ullNpx2iyqDdkTDACgokuY s7Uxb7EkItL3ksJQtdRZMXk= =qO+V -----END PGP MESSAGE----- ------------D515224B21B865FA--
