Well isn't this a nice familiar site...someone says blah blah blah and another says you are wrong, blah blah blah...

and now sorry for being off topic *ahem!*...

but anyone noticing that their Jupiters stop hashing randomly? The miner webpage inaccessible and the putty window crashes. When i reboot it starts up fine again, but 2 of the 3 crashed again after 4 hours. Will keep track of how long it takes for the next crash.

I get this maybe once every two days.

Seems likely it is same problem I have: running out of RAM. The handler for that chooses something to kill and does nto always kill cgminer, last time mine had that it was something to do with the web page that was killed so instead of a working web page saying the miner was stopped I had a not-working web page. Actually maybe even a cannot be pinged machine. I powered down and back up to get it running again.

I think we need a new "firmware" upgrade that gets rid of any RAM usage that isn't absolutely system-critical, as software bloat seems to have hit the limits of the beaglebone's RAM or some item of software in there has a memory leak.

Interestingly somewhere between 12 and 24 hours it killed the cgminer I was running 3.7.2 and ran the default one instead. Huh
