I have seen in the last few weeks that when I run Setiathome on 10.9.4 it eats up a TON of memory. So much, that it pretty much brings my mac to a halt. I have TWO Macs with over 8 gigs of memory that were just sitting idle, as they do, when this happens. It's a rather recent behavior, maybe happening around the last Apple system update?

Anyhow, I have to disable Setiathome now because of this. Anyone else seeing the program do this?

Have you tried restricting the number of cores that Boinc can use to see if it helps resolve this problem? I've had similar episodes but restricting the number seem to help somewhat. Just curious what does your activity monitor say when this happens? Are you forced to do a hard reboot when it happens? or can you shut off Boinc when it happens?

I had the same problem. I fixed it my running the BOINC un installer and trashing the BOINC data folder and then re installing 7.4.12 Runs fine now.

I have an 8 core MacPro, and I have it set to use 2 processors.

When i have monitored it in activity monitor, it looks fine. It's when I'm not there and let it run by itself for a few hours do I come back and have a Mac I have to hard reboot.

I had something similar but wasn't sure how to find what the problem was. Tbar is good source of information with the Macs and especially any with AMD GPUs. Here was his response. Next time it locks up, after the reboot check here

Go to Utilities/Console/All Messages and see if there is anything in there.

See if you find any report that might help point us in the right direction.
