Hi All, I've got the below system setup that has so far been very stable when running with 2GB of RAM. I've recently been attempting to upgrade it to 4GB of ram (using 4 DIMMs vs the current 2). The problem is that within a few hours of running with the 4GB config I start getting odd network errors. There's nothing in the logs, but incoming ssh connections start failing with errors like (Bad Packet Length) and things like ftp and nfs all fail in odd ways. As far as I can tell the RAM is fine, I've ran it through a few diff RAM testing utilities and it all comes out fine. I've also successfully run both sets of DIMMs by themselves, so at least it seems that this isn't a hardware problem. I'd appreciate any suggestions on tracking down the problem, again the logs don't seem to have any useful info on it. -- Paul Haddad (paul.haddad@gmail.com paul@pth.com) Copyright (c) 1992-2008 The FreeBSD Project.
