There were enormous efforts in improving FreeBSD 5.x, so if you already broke your system take the chance and get the new 5.4 system which probably fixes your problem. Next thing is that you won't see any benefit when enabling hyperthreading. It's strongly depending on the system's kind of load but almost everytime you'll see performance degradation. > The system was very stable with FreeBSD 4.10 and only 2 CPUs (1 real and > 1 virtual).

Does the fact to Maybe, but first you have to provide more information and make sure it frequently crashes at different points. Keep patience till anyone of the experts answers, in the meantime you can have a look at http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html for providing more information. -Mano > add 2 new CPUs is more likely to reveal a RAM problem that was not known > before? > > Thanks > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBCLmh1Bylq0S4AzzwRAgtzAKCHNeSTMwXoXoJcasUkUjHm5JVsPACdGJFL sWvUDib28H95YvpVgpwAd44= =VZ6l -----END PGP SIGNATURE-----
