Comment 3 Jiri Rechtacek 2008-09-29 13:05:33 UTC
Most of memory consumption was fixed in issue 124482, the expensive DOM parser was replaced by liter SAX parser. But
still parsing of content Update Centers need a plenty of memory, the biggest part of memory is taken by plugin's
licenses. For a next releases would be best to separate off licenses from Update Center Descriptor and handle them
separately from UCs.

Comment 5 Antonin Nebuzelsky 2008-11-14 15:32:50 UTC
Reassigning to the new "autoupdate/*" owner dlipin.
Comment 6 dlipin 2009-03-02 12:46:44 UTC
To significantly decrease the possibility of OOMs while dealing with plugins` licenses we can also dump licenses to 
disk while parsing catalog, and then retrieving (reading from disk) them on demand. This will help to avoid storing all 
licenses contents in memory. Certainly, such handling will be a little bit slower that existing one.

The proposed patch (can be with bugs) is attached.

It is not fixed. Still occurred in 200903060201 build. See http://www.netbeans.org/issues/show_bug.cgi?id=166725
Comment 11 dlipin 2009-06-08 15:52:55 UTC
Build 200903060201 belongs to the 6.5(.1) codeline which is handled separately from 6.7. 

This issue is fixed in recent daily builds and also in 6.7 M3, 6.7 Beta, 6.7 RCx and all futher 6.7 and post-6.7 builds.
