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.

I get hashrate with
'api-cgminer devs'

Get VRM details and clock volt temp stuff same as Advanced
'waas -g all-asic-info'
This also identifies choices for filtering.

To filter out Frequency
'waas -g all-asic-info | grep Freq'

or a different way to see clock only
'cat /var/volatile/run/.waas_curfreq'

The teaser
Code:
root@Neptune:~# cat /var/run/.waas_curfreq
-1 -1 -1 -1 500 500 550 500 500 500 525 525 500 500 550 500 475 500 525 500 475 525 500 525

Find sleeping VRM
'waas -g all-asic-info | grep Iout'

Change things manually instead of Advanced page
'vi /config/advanced.conf'

apply button replacement, use after manual edit of /config/advanced.conf
'waas'
WARNING this may result just like clicking on Apply in the advanced page with some VRM off.
It's random same as Advanced.

YMMV

EDIT
I found a way to wake up sleeping VRM
WITHOUT POWER CYCLE!
it's faster!

stop cgminer with
'/etc/init.d/cgminer.sh stop'
if Advanced page is open wait for numbers to drop (20 seconds?)
To just wake up sleepers no changes
'waas'
If you need to apply changes from Advanced do it with cgminer stopped
If you manually edited /config/advanced.conf, run
'waas'
Wait 20-30 seconds for waas to finish.
restart cgminer with
'/etc/init.d/cgminer.sh restart'
look to see if VRM are happy!
