For the last few months, I have continued my tradition of exiting SAGE whenever memory gets eaten up. When I need to solve a particularly large matrix system, I definitely exit and restart.
Well, I had been naively blaming the problem on SAGE, but now that I know a little better, it would appear that the problem is in python. Therefore, the real question is, how do I force python to free memory? There are lots of articles I've found in a Google search that seem to address the issue, so now I just need to find a solution. It may be as simple as a python upgrade, or it may be more complex. I did find mention of a garbage collection scheme, which I'm hoping I can access from the SAGE prompt. (One thing I did notice is that lists supposedly are handled relatively efficiently, and I tend to make use of vectors, so perhaps I need to rethink my strategy?)
For now, I'm sticking with the old standby: restarting often.
