I'm afraid our documentation isn't as complete as we would like. I will add
some documentation for this.

Why do you need to reload the catalogs? Sorry if I'm forgetting details we've
already discussed. Are you aggregating datasets? Is the problem something that
the "recheckEvery" attribute on the "aggregation" element won't handle?
"Aggregation on dynamic sets of files"

We have seen similar issues having to do with the JVM PermGen memory. Are you
getting "java.lang.OutOfMemoryError: PermGen space" messages? If so, try
increasing the PermGen space with the "-XX:MaxPermSize".

I'll answer the rest of your questions in another email (probably tomorrow).
