I have annotated my modifications to mongo's mount handling with 'dmd.' There are other non-annotated changes I have made, but they are not germane to this issue. If you want to know exactly what is different, diff this with the mongo.pl in the build Elena recently uploaded at http://thebsh.namesys.com/benchmarks/mongo-2004.07.26.tar.gz. I'm still rerunning tests to see if I can reproduce, but time is limited this weekend. David
