RSE 3.0M4, PHPEclpise-1.2.0 I have a large workspace with one project that includes a remote folder via an RSE SSH connection. Below that remote folder, there is a pretty large hierarchy of files. I had to quit Eclipse due to a hangup, added com.jcraft.jsch_0.1.37.jar and restarted with -clean. During startup, Eclipse hangs with this thread dump: it looks like no thread can signal on the Jobs semaphore that the main thread is holding, because there are two Worker jobs waiting on syncExec() which they cannot do because the main thread is stalled. What's more, bundle activation is not yet complete and the "files.ui adapter loader" is also stalled on a Job. The bug could be related to incorrect adatper factory loading (bug 218304). The deadlock is reproducable and happens when the splash screen shows "loading org.eclipse.rse.files.ui". Not even switching Eclipse installation helped, the issue is with the workspace. What finally helped was physically renaming the folder that holds the remote linked resources, such that Eclipse could no longer try and open it on startup. Closer investigation pending. 4144 eclipse.exe ( GDI+ Window ) session:0 threads:25 parent:6720 2008-02-08 22:16:20 Full thread dump Java HotSpot(TM) Client VM (1.6.0_02-b06 mixed mode): "StackTrace Remote Thread" prio=6 tid=0x03677c00 nid=0x1054 waiting on condition [0x00000000..0x05f1fa7c] java.lang.Thread.State: RUNNABLE "JMX server connection timeout 29" daemon prio=6 tid=0x037dac00 nid=0x17f8 in Object.wait() [0x05cff000..0x05cffc14] java.lang.Thread.State: TIMED_WAITING (on object monitor) at java.lang.Object.wait(Native Method) at com.sun.jmx.remote.internal.ServerCommunicatorAdmin$Timeout.run(ServerCommunicatorAdmin.java:150) -

Experienced a similar hang on "Import Existing Project", see bug 219164.
Moving severity down to "Major" since no loss of data occurred, there is a workaround, and the stalled workspace can be cleaned and re-created.
I've been re-creating the scenario with a smaller remote files tree and a faster connection, and it's been working very well. It looks like there is no deadlock involved, but only refresh of the large file tree on a slow connection takes long; and, depending on the situation, refresh can happen in the dispatch thread. This is really a problem of the Eclipse Workspace / Resources mechanism, and may partially even be impossible to fix under all circumstances. I'm describing the situation on the Known Issues and Workarounds page for now: http://wiki.eclipse.org/TM_3.0_Known_Issues_and_Workarounds In general, linking large file trees on slow connections into the Eclipse Workspace is discouraged. The RSE SystemView should be used for such slow remote resources, since it avoids unnecessary refresh and works more lazily.
Here's a concrete example: Refresh of a Linked resource to dsdp.eclipse.org:/home/www-data/build/dsdp/tm/rse/downloads/drops/3.0.0 --> 5237 folders --> 25890 files over an SSH connection from Salzburg, Austria took 2 hours 20 minutes to complete (connection speed was approx 100 KB/sec with a huge scp upload running in parallel over the same connection). The refresh operation could be "Canceled" but it could not be put into background to allow working on different parts of the project at the same time. Importing this project into a fresh workspace (or opening the first time, or opening after a Refresh had been canceled) would have blocked all of Eclipse without any chance to do anything else, and without any chance to cancel the operation.
For a discussion about improving the situation from TM / RSE, see http://dev.eclipse.org/mhonarc/lists/dsdp-tm-dev/msg01699.html , bug 195997, and bug 185925
