Re: Stability Under Load

When doing big compile jobs, the compiler would relatively regularly segfault or detect hardware errors, or errors it didn't think was hardware and invited me to post a bug report with pre-processed C file. None of these were reproducible (it would error out in a different place on different runs). So I figured I had duff hardware and got another one. This is a lot better, but I still get spurious, unreproducible errors like this every few hours (old one would error out up to a few times/hour if it was being hammered with compiling jobs for a few hours). Both of mine are the 10U models with Micron RAM.

I get some odd errors after I've left my TrimSlice on for a long time but haven't seen the things you're seeing. I'll do a big compile job and see if I can reproduce this because I think this is the same chip as the AC100. I also have an AC100 at home that I've been meaning to finish a Debian install on but we have a baby due so it turns out there are other priorities in life, according to my wife. (Who knew there was _anything_ more important than Linux?)
