Does this error also end up in the log files? If so, my first thought is that if you were able to (dared to) run the latest CVS version, you could configure Log4J to log errors from org.apache.jetspeed.services.profiler.JetspeedProfilerService to an appender that you could set up to send data to some listening application, either something like ChainSaw or a syslog daemon. If this is doable, let me know and I can give you some more pointers. This detailed logging configuration is only avaiable with the latest CVS version. I think the plan is to have a relase during this month.
