You don't need to post all your code, just a small example that demonstrates the problem you are experiencing.
If your computation is using half the memory on the machine, the solution is likely going to be to find a way to make it use less memory or to get a machine with more memory. The behaviour you've described so far seems wholly consistent with how Python handles objects, how garbage collectors work and how various libraries used by Sage handle memory. So far it doesn't sound like a bug to me. Bill. On Wednesday, 28 September 2016 14:08:09 UTC+2, Denis wrote: > > > Jonathan, thank you for this thoughtful analysis.
