After great help ( problems solved / many thanks for this ) for my first two announced bugs, i will continue bug reporting. Eclipse sometimes stop reacting on any input ( mouse or keyboard ) The only thing that works most time anyway is the icon( "x" ) to close eclipse. Then the message box "Confirm exit" appears. But if I press Ok, eclipse will not close. But somtimes eclipse get's live back and i can continue using it. If this dosn't work I have to kill eclipse with "<Strg>+<Alt>+<Esc>". After starting Eclipse again, sometimes it works fine, other times it freeze in at once. The worst case is when eclipse freeze in after changing some sources without saving. In the log file there is the following Error: < Error > "java.lang.OutOfMemoryError: unable to create new native thread" </ Error > I can't belive that memory is really a problem, because i'm working on a very small project and started Eclipse with the parameter for additional memory: "$ECLIPSE/eclipse -vm $JAVA_PATH -data $WORKSPACE -vmargs -Xmx256M" After i started eclipse. Ktop tells me, that there is more than 650 MB free. Here is some Information about my System: I'm using Suse Linux 7.3 kernel version 2.4.20 1 GHz Athlon with 1 GB RAM For my Eclipse Installation, i installed the following files: eclipse-SDK-RC1-linux-gtk.zip org.eclipse.cdt-200212181139-linux-gtk_1.0.1.bin.dist.zip org.eclipse.cdt-linux-gtk_1.0.1.bin.dist.zip atk-1.2.0.tar.bz2 pango-1.0.5.tar.bz2 pango-1.2.1.tar.bz2 glib-2.2.1.tar.bz2 gtk+-2.2.1.tar.bz2 pkgconfig-0.14.0.tar.gz tiff-v3.5.7.tar.gz jpegsrc.v6b.tar.gz libpng-1.2.5.tar.gz j2sdk-1_4_1_01-linux-i586-rpm.bin j2sdk-1_4_1-doc.zip gdb-5.3.tar.gz I installed the above mentioned file "org.eclipse.cdt-200212181139-linux-gtk_1.0.1.bin.dist.zip" after i recognized that in the install configuration of the "Eclipse C/C++ Development Tools 1.0.1" was somthing wrong. When i viewed the "Detail" from "Show Status" menu, i get the information, that the feature is not properly configured. After installing the File this mistake was gone. But my main error described at the top unfortunately stays. Ok, here are some sessions of the log file with the error: < Log-File > !ENTRY org.eclipse.ui 4 4 Mrz 05, 2003 12:13:13.717 !MESSAGE Unhandled exception caught in event loop. !ENTRY org.eclipse.ui 4 0

Both stack traces indicate that an attempt to create a new thread failed. The thread is used to get the features to show in Update's ConfigurationView without blocking the UI. This is new code. Perhaps these threads are hanging around and the system eventually runs out. If you run eclipse with a console VM (java rather than javaw), you can hit Ctrl+Break in the console VM to get a dump of all threads. The next time this happens, could you please try this and attach the results.
We dispatch remote connection to a worker thread because in case of a frozen connection it can block the UI. Typically, this connection times out eventually and the thread exits through the nature death. Occasionally, connections block indefinitely. You should check the URL you are trying to connect without success. Our connection manager has a limit of 10 threads before it refuses to create any more. Looks like you hit the 'out of memory' state before we hit our limit. Your main problem is the connection that refuses to time out. If you have such a problem, don't try to connect over and over because you will have more threads hanging around waiting for time out. We could kill the threads but according to Java documentation, it is not a safe operation and should be avoided. They recommend exactly what we do: allowing the thread to exit on its own.
I found out, if eclipse freeze in with every new start, it helps if you delete the ".metadata" directory in your workspace. But unfortunately all your configuration is lost with this operation. So if you need, do a backup of the directory before deleting it. If you haven't configured to much, you can easily import your existing projects, and resume working. If somebody wants to do a thread dump on a linux System as described in http://bugs.eclipse.org/bugs/show_bug.cgi?id=33836#c1 for german Keyboard you have to press "<Strg>+<Alt Gr>+<ß>".

There are no Update threads in the last dump.
Strange that there's a scrollbar event coming in while in the Confirm Exit dialog, since it is a modal dialog and has no scrollbars. Moving to SWT since they're looking at several issues with GTK 2.2.1.
The reason why there are no update threads in my thread dump could be that i was starting eclipse a few times without trying to search for an update. But the extract of my Log file shows a session where i tried to update eclipse and where eclipse frozes in a little bit later. At the Moment I'm using an older Version of eclipse ( M4 ) because ( RC1 ) freezes in even after deleting the .metadata directory in a very short time. At the moment I noticed, that there is the new Release ( RC2 ). I will test it. Maybe the problems are already solved in this version.
Do you have a repeatable test case for this? What theme are you using (if any)?
Created attachment 3952 [details] workspace which freezes in Eclipse (RC1) after starting it. This is my damaged workspace. If you want to see Eclipse freezing in, just start Eclipse (RC1) with the unpacked attachment as workspace. Move your mouse to the scroll bar of the opend cpp editor window. Try to scroll the Text. That's it. On my Computer the text will not scroll and you can't even exit Eclipse anymore.
If you mean GTK-Themes. I think I use no themes. Can't remember that I ever downloaded or configured somthing like this. The only thing I tried is to change the Background color of eclipse with System-Colour Settings. But didn't work although i enabled the checkbox "Apply fonts and colors to non-KDE apps" in the "style" settings. In eclipse I changed the "Text Font" Size to 12 point. ("Preferences"->"Workbench"->"Fonts")
I think this problem report is a dup of Bug#33652. Again, the gtk_main_do_event shows up in the stack trace. I've seen this same function causing problems on Bug#33017 comment 8 and Bug#33652 comment 38.
