I'm having a problem with my sun (SUN ULTRA 5/10 UPA/PCI (ULTRASPARC - IIi 440 MHz)) this computer stays days without any crash even in 100% of processing but some days, i don't know why the machine stops and doesn't work unless i reboot it ... i think it's a cache problem my teacher saw on internet that there might be a incompability betwen the mother board and the cpu of this machine he asked me to solve this problem but i don't know what to do... can anybody help me?

its not supposed to be on 100% processing all the time (or 100%load) do you leave it connected to broadband all the time? download adawareSE and spybotS&D and CWShredder to see if you have any spyware. sounds like you do - even if you have to download them from another computer,save the .exe file to cd and then install it on the 'sun' computer. post on the security forum if you have probs/queries with those 2 programs

I don't think he has spyware, if you do a lot of rendering compiling or anything processor heavy it'll take up 100%. Just the otherday i left my computer on for 4 days straight rendering a project it was at like 99% for most of the time. About his problem i have no idea.

true (on a 440mhz?) only 1 person who can tell us what they use the machine for.... always a good idea to have those anti-spware stuff running of you have broadband anyway.

Hey guys, this Sun workstation is running Solaris (or at least is so indicated), and if I'm not mistaken, these spyware detectors won't run on anything but x86 machines running Windows. It's likely unnecessary on that machine, anyway. If you think it's a cache problem, Lakos, then disable the cache. I tend to doubt it's a motherboard/CPU incompatibility if the machine runs fine for periods at a time, then mysteriously needs to be rebooted. Maybe you have some flaky hardware (RAM, maybe). You might try swapping out a piece of hardware to possibly isolate the problem. Of course, it could be a software issue. Are you running something that isn't being run on similar machines that aren't "crashing", and that piece of software is buggy? (Of course, that shouldn't stop Solaris dead in its tracks unless it's corrupting something in core). When you say it "crashes", can you get to a console and kill the offending process, or is the machine completely hung (locked up)? Good luck.

I'm trying to get more info about the machine in a few days will give a full report about the machine... i will try to change the ram to see what happens thanks guys!!!
