I haven't downgraded yet (Dad getting out of the hospital, built-in microwave from the honeydew list, the holiday and baby-girl's 4th birthday,... yes, that's how old my profile pic is),... I can try to stress-test the system, if you tell me what and where to pull log files from...
My system doesn't crap out with any consistency, but I can try taxing it by having a couple of the MD's playing live TV over night... It tends to do it when it's been on Live TV for an extended period of time... But it's hit and miss.
Just let me know what and where to pull logs from,... and I'll see what I can do...
