[Mesa-users] Crash after 8.1e6 yrs on 20 m simulation

[Francis Timmes]

that is a small amount of ram for the os and running other applications.
i suspect your machine is page faulting (going to disk instead of ram) a lot.

fxt

p.s. - always cc mesa-users in replies so that things are tracked.

I tried to do a ./clean and then reinstall. I tried trimming all of my options down and just running the code 'bare-bones', but still get this crash (after the sim has run for a while, around 8 million years time frame) and error.
