`x^4+y^4+z^4-67*t^4 in ideal(f1,f2)`
This leaks about 2MB memory per second, presumably because the Groebner bases for the ideals are being cached; is there a way to tell sage not to cache them?Tue, 17 Jan 2012 06:59:06 +0100https://ask.sagemath.org/question/8573/memory-leak-when-doing-lots-of-ideal-tests/Comment by Anakonda for <p>I'm trying to find elliptic curves lying on a quartic surface; there are probably clever ways to do this, but at the moment I am finding lots of quadrics through an integer point on the surface, then iterating over pairs of them and checking</p>

https://ask.sagemath.org/question/8573/memory-leak-when-doing-lots-of-ideal-tests/?comment=18747#post-id-18747I have the same problem now (iterating over some polynomials, the memory for the groebner base is not freed). I'm thinking about filing a bug report. Did you find any solution?Tue, 06 Nov 2012 15:00:53 +0100https://ask.sagemath.org/question/8573/memory-leak-when-doing-lots-of-ideal-tests/?comment=18747#post-id-18747
