No. And there are no Apache processes running. I have to manually
start apache everytime.

It starts a new log, and starts with this:
[Sun Jan 5 13:52:10 2003] [warn] pid file /var/run/apache.pid
overwritten -- Unclean shutdown of previous Apache run?
[Sun Jan 5 13:52:11 2003] [notice] Apache/1.3.26 (Unix) Debian
GNU/Linux mod_ssl/2.8.9 OpenSSL/0.9.6g PHP/4.1.2 configured --
resuming normal operations
[Sun Jan 5 13:52:11 2003] [notice] suEXEC mechanism enabled (wrapper:
/usr/lib/apache/suexec)
[Sun Jan 5 13:52:11 2003] [notice] Accept mutex: sysvsem (Default:
sysvsem)
That was when I first caught apache not running on the 5th of Jan.

After a log is rotated, logrotate suggests restarting any service that
"belongs" to the log. It seems to work fine on 4 other boxes, and this
one is the only one that fails. The only difference is that this box
runs sarge and the others are woody. I have searched the bug reports
for both apache and logrotate, and have not found any results that
match.
