I doubled my swap space from @512MB to to 1GB. Now the system seems to be more stable. So far no crash or lockout. > Anything else to be considered? > systat is included in the package "procps".

How and why is a different topic. Yes, Google. Thanks for the tips. Thanks, -Kshitij

How long did you run it? I usually test at least 24 hours to a full weekend when I'm troubleshooting a system with intermittent crashes. A weak bit may only 'hiccup' once every X exercises, under exact conditions (temp and voltage) so you need to let it run enough passes. The longer you run it and encounter zero errors, the more confidence you can have in the result.

Glad to hear it. Although 'stable' is like 'pregnant'... you either are, or you aren't ;-) There isn't a lot of middle ground, at least in hardware. Is anything else different? Weather? Ventillation? AC power? Did you remove and then re-seat the modules? I've seen new modules not "bite" fully into the slot until inserted and removed a few times... contaminants from manufacturing, dust, that kind of thing... Anyway, sounds good so far.
Thanks for the tips.
You're welcome & good luck! - Carl
