What JVM are you using?  Older ones have been known to have long pauses
for garbage collection, but even then 30 seconds would be quite unusual.

Regarding the logging: additional logging may make the problem worse,
depending on what's actually causing the problem.  Strongly suggest
poking around with JConsole first to see what's going on, paying close
attention to the state of the heap and looking at stack traces of the
worker threads.
