I've restarted the Galileo help instance.

-M.
Comment 2 Martin Oberhuber CLA 2010-04-29 01:26:50 EDT 
Out of curiosity, what memory args does the helpserver run with? eg
  -vmargs -Xmx512m -XX:MaxPermSizer=256m

I have seen the Lucene indexer take a surprisingly large amount of memory, such that the default vmargs were not sufficient even on a relatively small help server.

Also, to avoid / diagnose problems in the future, I would suggest running with a JVM option that dumps the heap on out-of-memory:

  http://wiki.eclipse.org/index.php/MemoryAnalyzer#IBM_Java_5.0_and_Java_6_Virtual_Machine_dump_options

Such a heap dump can be analyzed very quickly and easily to see what caused the Out-of-memory-error.

It's not using any specific memory settings...
