One of my co-workers ran the test so I'm not entirely sure, but I'm pretty certain it was at least over night (so probably 15-16 hours). We also ended up swapping that RAM out with another box and the problem did not move to the new box. > 1. did you try to swap the mainboard? Yeah we actually ended up buying an entirely new chassis (MB, power supplies, case). > 2. do you suspect any corelation between net traffic intensity,type,etc, > and crashes? It is possible because we do a TON of traffic through these boxes, but things like mbufs and other limited resources seem to be ok. It is definitely possible I'm not looking in the right place for something else that would be causing this. However, as I mentioned earlier, this is one box out of a farm that is acting particularly less stable and all the boxes should ideally be receiving similar traffic loads. > 3. disabling ACPI made no change? Disabling ACPI resolved a number of noisy boot time messages, but didn't give us any noticeable edge in stability. Now that the long weekend is over I'll likely have some time to try a few more things related to the drive. I suspect I might have inadvertently introduced a negative variable in the drive swapping I did. I'd like to make this last change before digging too much deeper unless the trace data gives anyone else any clues. Thanks everyone for you input.
