Finally was able to get my xubuntu mining rig upgraded to cgminer 2.7.6 from 2.4.1. The precompiled binaries no longer run on that version of xubuntu so it was a pita process of compiling manually. From what I've read in here those older versions of cgminer were causing server resource issues, so that should help a tiny bit.
Eh? Which xubuntu?
11.04. Yea, old version I know but I don't want to deal with the driver and sdk performance issues on the newer versions, which is why I haven't upgraded it. I'm sorry I didn't save the exact message, I figured the problem was solely because I needed to upgrade xubuntu and not a cgminer problem. I can try attempting to run the precompiled version again though to see if I can recreate the error.
Umm - obviously you don't read the cgminer thread

(or look at my sig ... OK it is chopped off at the moment ... blame Transisto)
I create one of these posts each time cgminer is released (since 2.4.3)

Absolutely no changes to anything required except a single cgminer binary (from my downloads) to add to your current full matching version number binary download from ckolivas
