Mike Pilato and I had a theory about this, maybe someone more familiar
with Apache 2 can comment:

`logrotate' rotates the logs at midnight on the first of each month
(or whenever, not sure of the exact time). Now, if Apache happens to
remain running during that rotation, and keeps its file descriptors
open on the various logfiles, then when `logrotate' renames a file
from `foo.log' to `foo.log.1', Apache won't ever know that the rename
has taken place, and will just be logging in `foo.log.1' from that
moment forward. The log file's dir entry has changed, but the
filehandle has not. Apache would need to close and reopen the log
file at the same time as logrotate rotates it, for things to work
correctly. (Well, hopefully there's a better solution than that...)

Can this be what's happening?
