I am experiencing Eclipse 3.2.2 going to 100% CPU with Subclipse 1.2.2.
This is under Windows XP. Task Manager shows lots of system time going
on (say 70% red 30% in the 'performance' tab). Progress monitor often
reported SVNStatusSubscriber running very slowly. I tried both JavaHL
and SVNKit - both fail in same way. I have bumped up memory for Eclipse
(some people were getting 100% CPU due to lack of memory). I don't
think its memory limit related.
I now think I know the situation in which I create it. I have a Maven
product with multiple modules. I was using m2eclipse, but it frequently
plays up (does not work out dependencies correctly) and after spending
up to an hour a day hitting F5 and restarting Eclipse until it suddenly
starts working for no apparent reason, I read another way of doing Maven
with Eclipse was to svn check out all the code under a tree outside the
Eclipse Workspace and then run mvn eclipse:eclipse to create .project
files for each module. I can then import all these modules. This means
I have projects in the workspace, but which refer to the source code off
in another directory tree. Things seem to work fine, but I lose the
Subclipse branch/tag/switch etc capability for the whole directory
tree. So on the web I read a suggestion to import each module as a
project *AND* import the root directory as a project as well. This is
possible with the newer versions of Eclipse. That is, the directory
trees of the source code overlap. I can then use the root project for
doing svn branch/tag etc commands. I can also use the individual
projects with their individual classpaths set up by mvn eclipse:eclipse
- no more need for the m2eclipse plugin.
HOWEVER, it appears that as soon as I create the root project in Eclipse
that overlaps the existing projects for all the modules, subclipse goes
insane. I suspect it gets confused by the projects with overlapping
source trees. As soon as I delete the root project, Eclipse CPU shortly
after drops to 0% again. Sometimes the delete comes up with an error
also talking about SVNStatusSubscriber errors (but does delete).
Any help greatly appreciated!

PS: I have a number of errors in the Eclipse log file
(workspace/.metadata/.log). Here is the last entry.
