I would start by turning off Hyperthreading as that only really works if you are using the ULE scheduler and thats broken under RELENG_5. Try rebuilding a uniprocessor kernel and see if the problem is still there. Also, enable crash dumps on the box to see if it's a bug or not. Rarely have I seen random reboots with no crash dump be a software issue. See http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kern= eldebug.html for info on how to enable crash dumps. I would also update to 5.4 as there are a number of bug fixes you might benefit from depending on how old your build is. =20 ---Mike -------------------------------------------------------- Mike Tancsa, Sentex communications http://www.sentex.net Providing Internet Access since 1994 mike@sentex.net, (http://www.tancsa.com)
