It sounded similar to [this](https://github.com/cvxgrp/cvxpy/issues/166) issue which was apparently resolved, but when I ran the same code snippet from the resolved issue on my computer I noticed that memory usage (monitored through >> top) still seems to be increasing with the loop. For prob.solve() with arguments CVXOPT, ECOS, SCS, or no argument, memory usage increased from about 40 kB at the start to about 300 kB after the last loop. While 300 kB isn't a huge deal for this test case of 10000 loops, it turns into tens of GB after billions of loops.\r\n\r\nI posted this issue to the cvxpy Google Groups and was told that it might be an issue with CVXcanon, so I'm reposting the question here."},"comment":{"url":"https://api.github.com/repos/cvxgrp/CVXcanon/issues/comments/223065777","html_url":"https://github.com/cvxgrp/CVXcanon/issues/23#issuecomment-223065777","issue_url":"https://api.github.com/repos/cvxgrp/CVXcanon/issues/23","id":223065777,"user":{"login":"mwytock","id":591830,"avatar_url":"https://avatars.githubusercontent.com/u/591830?v=3","gravatar_id":"","url":"https://api.github.com/users/mwytock","html_url":"https://github.com/mwytock","followers_url":"https://api.github.com/users/mwytock/followers","following_url":"https://api.github.com/users/mwytock/following{/other_user}","gists_url":"https://api.github.com/users/mwytock/gists{/gist_id}","starred_url":"https://api.github.com/users/mwytock/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mwytock/subscriptions","organizations_url":"https://api.github.com/users/mwytock/orgs","repos_url":"https://api.github.com/users/mwytock/repos","events_url":"https://api.github.com/users/mwytock/events{/privacy}","received_events_url":"https://api.github.com/users/mwytock/received_events","type":"User","site_admin":false},"created_at":"2016-06-01T17:28:39Z","updated_at":"2016-06-01T17:28:39Z","body":"https://github.com/cvxgrp/cvxpy/issues/283"}}
