Hi, I have now committed a fix on trunk of some errors in the interrupt handling of RAFContainer4 as part of DERBY-4741. We saw hangs in suitesAll (DERBY-4920) prior to that check-in (svn 1040086); I am now looking for instances of the hang *after* 1040086 went in.
Please let me know if you still see it, as I doubt 1040086 fixed the root cause of DERBY-4741, with as much detail as you can provide (e.g. jps, jstack). Meanwhile I am thinking about a way to instrument the code to catch the issue. Thanks, Dag
