Importing large amounts of SVN data into Jazz SCM

I have a team in Toronto that is trying to import SVN data into RTC, and things are just not working right.  Some of this may be their environment, which we need to check out.  These guys claim that the Eclipse client keeps on crashing whenever they attempt to do imports from SVN.  They are on RTC 4.0.2., and are running with DB2 Express-C as the DB.  RTC is running on a VM running Redhat, with 6GB of memory, and 4 cores.

has anyone seen anything like this?

Hi Daniel,
If this is a crash, you should look into cores generated to see which method is already crashing. Have you already done that?
You can also consider opening new PMR for that.

 Hi Dan,  we've seen a few problems importing large SVN dump files into RTC.  Some of these have ended up being defects some have been addressed via temporary JVM settings in the eclipse.ini for the RTC client.    Some work items that come to mind: Performance issues importing large SVN dump file. (251948) That is in the private support PA.  It would be useful to look at their eclipse .log file too to see what type of exceptions they are running into.  If the client is crashing I'm wondering if they are hitting an out of memory type exception.

 To follow up Josh's comment it would be very useful to examine the eclipse log. I have experienced situations where it ran out of java heap and we were at the limit on 32 bit windows system see: http://stackoverflow.com/questions/2457514/understanding-max-jvm-heap-size-32bit-vs-64bit/ 
Switching to a 64 bit Eclipse and JRE allowed us to allocate more heap.
