User Comments:
GUEST: had a log .txt file opened in a tab, switched to browser and generated more logs and switched back to nb with that file opened. wasn't more than 1mb of txt in there :|

GUEST: I was running a program executing a relatively large (~1000lines) XSLT with XALAN

GUEST: nothing special, just coding a little bit php

GUEST: leave NetBeans on for nearly a week

rhj4: I clicked on a window containing a very large (3MB) file and program hung.

GUEST: Netbeans locked up upon running an app and took 5 minutes or so to come back.

GUEST: unresponsive ide

GUEST: halt error

GUEST: pasted if-else without closing } after which the IDE hanged

GUEST: NB was running over night.

GUEST: reading log files

GUEST: it took 2gb ram only on editing code ....shit ide

GUEST: Just trying to bring it to the foreground.

GUEST: working with 1MB xml file.  ide freezes after each edit.  had a 5 line change.  did an svn diff.. in the diff screen I tried commiting my change.. it said it needed an svn update so i clicked update.. afterwards I think I tried commiting.  I walked away from my desk. when I came back the xml file was showing as empty (no text in the file).  It was being sluggish by then.  I tried going to the file and hitting control-z to undo the text deletion. the IDE had frozen.  VisualVM showed the Perm generation was completely full!  (the xml file was the only file I had open in the ide)
