Mark is seeing a situa= tion where there is nothing on the AIL and is clogged up in the CIL, others are seeing items on the AIL that don't seem to be making progress. Could you provide a dump or traces from a hang on a filesystem with a normal sized lo= g? Can the reproducer hit the hang eventually without resorting to the tiny lo= g?
