I have a Mac OSX machine and I have not had one Model run for more than one minute in the last week. I look at the models and they are crashing not just for me but for all 3 supported OS's ( Win,Linux,and OSX). Has anyone found a reason for this?

EDIT just for emphasis none of the WU have been finished by any computer assigned to them. This is not an OSX problem. This appears to be a model problem.

Actually it IS a Mac problem, and is described in this sticky thread right at the top of the Macintosh section.

There is a different problem with some Linux systems, described in a sticky thread at the top of the Linux section.

Most Windows models run without problems.

The funny thing is I have done no system changes and my system was doing good work until mid to end of February last month and then nothing has worked since. I have done the detach reattach and am looking to see if this fixes the problem. I suspect it won't but am hoping it will.I looked at most of my failed work units and even the windows machines error out the WU that died on my machine. My task list

some WU that both a windows machine and mine killed
this one one of each OS killed it

Here on OSX and Window machine killed it

There's no need for more info.
It's well known that some hadcm3n models are very unstable for some reason, but these models haven't been available for some time now.

As for Mac computers, when BOINC went from 6.10.* to 6.12.*, the extra 'sandboxing' meant that some permissions would no longer work. I think it's because some parts got moved to different folders/sub folders.
However it was a long time back in terms of BOINC versions and talk about it on the BOINC/dev boards, and I don't have a Mac, so I wasn't interested in the fine details.

There's a very long thread in the climateprediction.net Science section of this board under Misconfiguration e-mail, which is a discussion thread for people who have had their computers blocked until they fixed the problem.
So we know that the disconnect/re-attach works. If it doesn't for you, then it's a first, so let us know.
