I just woke up, and saw that cgminer 4.4.1 dumped again (and restarted automatically)... looks that there is some bug in fw-1.0 or cgminer_4.4.1 (I didn't have crashes with rc9 and 4.4.0, while hardware and Volt-tuning are all the same).
Next week, I hope to have some more time and will check that log-file (thanks for the info).
Did you have Status or Advanced web page running?
ssh connection?
miner.php using the API?
I have stopped using the gui completely when possible.
Not even running 'screen -r'
I'll see how long going native lasts.
No, I don't use status/adv web-page, but I do run PuTTY with screen -dr.
Currently CGminer is running for 15 hours straight, but I expect some dump later (which isn't that problematic, as it auto-restarts).
