Uh.. excuse me if this dense, but why would the process still be writing
to the .0 file?  This file has already been rotated (i.e. it is already
once removed from the "active" logfile).  I've been running some fairly
high volume sendmail gateways for about 3 years now and have never noticed
a problem.  By the time that the .0 file -> .1.gz, it should be be quite
"dead."
