Cross" Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG We have been experiencing some problems with a 3.1-stable machine with 192M of RAM and 900M swap. The crashes seem to be related to NFS, but it is very eratic (oh, did I mention maxusers is 320?). Needless to say, we think the problem may be the KVA problem that has walked arround here abit lately. I have the patches from Tor Egge. I noticed that some of the patches are optional. For example, we don't need to make a change to pmap.h since we can do the same with 'options "NKPDE=126"'. However there are also changes to the kernel's load address (0xf0100000 -> 0xe0100000). Are these changes mandatory as well? (I am assuming they are, but we don't want to make changes to source files that CVS is going to blast.). -- David Cross To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
