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 ...
