Just to follow up on my findings on this. After a lot of reading,
searching and postulating the culprit turned out to be the DEBUG! As
soon as I turned debugging/logging off, all the problems went away. I
guess the DEBUG I/O was either hanging the system or just the software,
in either case, it was bad.
Thanks to all who offered assistance. I'm still considering upgrading to
2.3, but AFTER several other issues get resolved.
