Description Mikayla Hutchinson [MSFT] 2012-05-04 19:14:36 UTC
MonoDevelop is leaking heavily during normal usage, even with stetic disabled.
Comment 1 Alan McGovern 2013-01-14 09:57:29 UTC
Is this still the case? I've never been able to reproduce a noticeable leak. We may as well close this if we can't get more info.
Comment 2 Mikayla Hutchinson [MSFT] 2013-01-15 16:20:48 UTC
Yes. Every time I open and close Main.sln, MD's memory use grows another 30-100 MB, and it never goes back down.
Comment 3 Alan McGovern 2013-01-15 19:43:19 UTC
Does this only happen on MacOS or does it happen on windows too?
Comment 4 Alan McGovern 2013-01-15 19:57:37 UTC
I opened and closed main.sln several dozen times and saw a pretty negligible change in memory usage as compared to opening it just once. There's definitely a leak but it is miniscule, in the order of a few MB per open/close cycle you average out the memory increase.

If you can still repro 30-100 mb per open/close cycle with the latest builds we should look into it.

MacOS, tip of ui-refresh, bockbuild.

Michael, is this fixed?
Comment 8 Mikayla Hutchinson [MSFT] 2013-11-24 14:12:10 UTC
Can trivially repro on Windows. Simply keep opening and closing Main.sln.
Comment 9 Mike Krüger 2013-11-27 01:53:24 UTC
Comment 10 Alan McGovern 2013-11-27 20:48:54 UTC
The same bug still exists after your fix. The repro is even simpler. You can trigger it this way on Mac:

1) Delete ~/Library/Caches/XamarinStudio-4.0
2) Open XS
3) Open Main.sln (from the monodevelop repo) and the close it immediately


Memory usage increases forever and the CPU is consistently around 150%.
Comment 11 Mike Krüger 2013-11-28 01:21:43 UTC
It is not the same bug. That is completely different.
Comment 12 Mike Krüger 2013-11-28 01:36:15 UTC
(btw. that one should be fixed as well)
