After running RSE for some hours, eclipse started using more and more CPU time. In the Progress bar a lot "Resolve Filter String...Operation" jobs appeared (I was not able to make a screenshot, because my system became unusably slow even though I set the priority of the java process to idle). However, I was able to create a thread dump. There is a very deep recursion in RSE/SWT in the main thread. - locked <0x1db0d4d0> (a org.eclipse.swt.widgets.RunnableLock) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3325) at org.eclipse.swt.widgets.Display.msgFilterProc(Display.java:2758) at org.eclipse.swt.internal.win32.OS.TrackPopupMenu(Native Method) at org.eclipse.swt.widgets.Menu._setVisible(Menu.java:225) at org.eclipse.swt.widgets.Display.runPopups(Display.java:3374) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2962) at org.eclipse.rse.core.subsystems.SubSystem.scheduleJob(SubSystem.java:2110) at org.eclipse.rse.core.subsystems.SubSystem.resolveFilterStrings(SubSystem.java:2058) at org.eclipse.rse.ui.view.SystemViewFilterReferenceAdapter.internalGetChildren(SystemViewFilterReferenceAdapter.java:363) -

Created attachment 51575 [details] The eclipse Thread Dump Here is the thread dump of eclipse....
See bug 160111 for some more details.
Dave- I consider this critical, and bug 160111 has some details that should help finding the problem quickly.
This looks like it may be a duplicate of this one: https://bugs.eclipse.org/bugs/show_bug.cgi?id=150954 I'm assuming that the monitor view is polling when this happens. Is this correct?
I don't remember. But I see *lots* of problems related to the nested event loop. At the moment my eclipse does not exit because of this stack trace. The more I look into the code the more I get scared about threading and nested event loop issues. Does anybody really understand what is happening with treading? Just open a few connections and start clicking fast on some directories (to open), run a few monitors, run remote searches and you are guaranteed to hang. Actually I am having a hard time to find a "path" for my demo on Thursday where I don't hang RSE. at java.lang.Object.wait(Native Method) at org.eclipse.rse.services.dstore.util.DStoreStatusMonitor.waitForUpdate(DStoreStatusMonitor.java:383) - locked <0x151775b8> (a org.eclipse.rse.services.dstore.util.DStoreStatusMonitor) at org.eclipse.rse.services.dstore.util.DStoreStatusMonitor.waitForUpdate(DStoreStatusMonitor.java:308) - locked <0x151775b8> (a org.eclipse.rse.services.dstore.util.DStoreStatusMonitor) at org.eclipse.rse.services.dstore.util.DStoreStatusMonitor.waitForUpdate(DStoreStatusMonitor.java:252) at org.eclipse.rse.services.dstore.AbstractDStoreService.dsQueryCommand(AbstractDStoreService.java:87) at org.eclipse.rse.services.dstore.files.DStoreFileService.fetch(DStoreFileService.java:1210) at org.eclipse.rse.services.dstore.files.DStoreFileService.getFiles(DStoreFileService.java:1162) at org.eclipse.rse.subsystems.files.core.servicesubsystem.FileServiceSubSystem.getFiles(FileServiceSubSystem.java:297) at org.eclipse.rse.subsystems.files.core.servicesubsystem.FileServiceSubSystem.listFiles(FileServiceSubSystem.java:373) at org.eclipse.rse.subsystems.files.core.subsystems.RemoteFileSubSystem.listFiles(RemoteFileSubSystem.java:896) at org.eclipse.rse.subsystems.files.core.subsystems.RemoteFileSubSystem.listFiles(RemoteFileSubSystem.java:880) at org.eclipse.rse.subsystems.files.dstore.subsystem.DStoreFileSubSystemSearchResultConfiguration.getResults(DStoreFileSubSystemSearchResultConfiguration.java:83) at org.eclipse.rse.services.search.HostSearchResultSet.getAllResults(HostSearchResultSet.java:117) at org.eclipse.rse.ui.view.search.SystemSearchTableView.systemResourceChanged(SystemSearchTableView.java:302) at org.eclipse.rse.internal.model.SystemResourceChangeManager.notify(SystemResourceChangeManager.java:74) at org.eclipse.rse.model.SystemRegistry.fireEvent(SystemRegistry.java:2803) at org.eclipse.rse.subsystems.files.core.servicesubsystem.OutputRefresh.run(OutputRefresh.java:43) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123) - locked <0x107c0a40> (a org.eclipse.swt.widgets.RunnableLock) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3325) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2971) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1914) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1878) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:419) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:95) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:78) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:92) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:68) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:177) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:336) at org.eclipse.core.launcher.Main.basicRun(Main.java:280) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952)
Created attachment 51710 [details] another bad stack trace My system does not hang, but eclipse is blocking and hanging.
plus it cannot exit: I have to kill eclipse to exit. BTW I use the following too to get stack traces of a running eclipse http://www.adaptj.com/root/main/stacktrace Webstart: http://tmitevski.users.mcs2.netarray.com/stacktrace/app/launch.jnlp
I've got a fix for this now. We were firing a EVENT_REFRESH after doing a query which causes views to reissue the query. I've changed the event to EVENT_CHANGE_CHILDREN which just deals with redrawing.
I'll test it as soon as the build is available... The general problem of the nested event loops will be addressed in bug 160111?
I just saw your other comments here which would be separate issues I think from the monitor one. Could you open a separate defect for each of those separate scenarios (ones that don't involve the monitor view polling)?
[target cleanup] 1.0 RC2 was the original target milestone for this bug
