Chuck During my traineeship we had an PowerEdge 2650 (Dual Xeon with FreeBSD 5.1 at that time). The machine had quite high loads (8.00 - 11.00, which was 24/7), but it kept working most times. Sometimes after a few days or weeks it resulted in a panic. My mentor (who was the Unix specialist) said that it was probably been caused by the RAID controller as well. It was a PERC2/DC or PERC3/DC, not really sure. I think it's the latter. Anyway, when 5.2 came out, my mentor immediately upgraded to 5.2, and the machine became rock solid, even with very high loads. It was a monitoring machine, which collected over 1600 SMNP requests from every server, so I'm not really sure if that produces an high disk I/O or not. Perhaps the story is not interesting, but I felt like sharing that.

Re: FreeBSD 5.2.1 kernel w/ SMP under high load = panic
4.10 won't work with the current hardware on the server, and I wanted to try 5.2.1 because of the improved SMP. I know there is a solution for this by adding a kernel option, but i'm completely CLUELESS. Can anyone give a hint? -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On Sunday 01 August 2004 15:08, Hugo Silva wrote: I am running a Dual Xeon 2.8ghz w/ SMP, SCHED_ULE on FreeBSD 5.2.1-RELEASE-p9.

Re: FreeBSD 5.2.1 kernel w/ SMP under high load = panic
Damn. And any clue on the magic kernel option that stopped the panics? Perhaps it wasn't *that* magic and just decreased the odds of a panic hapenning under high load, but that would do for me. I just lost the server 10 minutes ago doing a portupgrade -a with 4 jails running. :x Regards, Hugo it was said: 4.10 won't work with the current hardware on the server, and I wanted to try 5.2.1 because of the improved SMP.
