Well, from your other e-mail it seems it was just dumping lots of old logs
since the previous clean shutdown.  (I almost mentioned that case in my
original e-mail).  In that case you can simply let it finish walking through
all the logs or you can set loader tunables to raise the minimum class of
message so it skips all the lower priority info messages when walking the
log.
