I am using the executable ckolivas most recently posted about, supposedly 3.7.1

I don't have an ARM development machine nor know a thing about cross-compiling on Fedora 17 or 19 for ARM machines.

I have run over 48 hours before dying sometimes, even over 72 maybe. Actually maybe it didn't die like this until they released a release that had a ckolivas version in it, hmm I wonder if that one is/was stripped? Hmm... I am not sure when I first encountered this "mystery dying" problem, seems liek it ran quite a few days originally.

I killed it to try running strip on it on the beaglebone, that is how I discovered they dont' seem to have strip on that. But now it shows in web page as 282 so maybe its not goign to lose much by using --lowmem option afterall. I do wonder how much RAM the debugging symbols are consuming though...

Hi Mark, just a FYI

Another 24 hours running the same setup (0.96 with 3.7.2 cgminer) and my memory footprint hasn't changed cgminer is still fluctuating between 23% and 25% memory.

However, overall system memory has dropped to only 127MB free. So something is using up memory on the system over time, but its not cgminer.

Now:

Code:
