Subject [jira] [Commented] (DIRSTUDIO-1119) Group (cn) with over 1000 members crashes

Stefan Seelmann commented on DIRSTUDIO-1119:

I tested on Linux. Opening a group with 1000 members works well. Also a group with 10k members
works but it takes approx. 10 seconds to open the entry. But what I see is that memory usage
increases, from 50MB to 230MB but after running GC most is free again, even if the 10k members
entry is still shown. So I assume we do some very inefficient things when loading the entry
into the editor, a quick look with JVisualVM proves that.

Can you check the memory consumption when opening groups with many members? In Preferences->General
please enable "Show heap status", then in the status bar you shouls see the memory usage.
You can also try to increase the memory (

> When opening a group object (cn) with over 1000 memberuid entries, the application locks,
refuses to cancel the activity, and requires a forced quit.
> Note, this does not affect a list of users, just elements within a cn.
> If more details are required, please let me know, I can always reproduce this bug.
