Re: Long fuzzy checkpoint

I think is unlikely that the problem is related to the fact this is a "fuzzy" checkpoint. If you don't see that the prolem is I/O, maybe th eproblem is that a thread is in critical section (look in onstat -u for a thread with the "X" flag). Then try to analyze what is this thread doing.
