Thanks for the response Tom.
The checkpoint process seems to be just sitting. I'll post the details
of strace/gdb in the morning.
Thanks again!

Is the checkpoint process actually doing anything, or just sitting?
(strace'ing it would reveal this) If it seems to be just sitting,
could you attach to it with gdb and get a stack trace to find out
where it's sitting?
The only known cause of checkpoints not proceeding in 7.4.* is that
long btree CREATE INDEX operations can block them. But 24 hours
sounds pretty long for a CREATE INDEX too ...
