We had a similar problem in CERN. Log files were not being rotated at all.
This was fixed by changing some setting in logrotate. Could you run the
logrotate script in test mode to see what is wrong? There seems to be an
unintended conflict of something the script does versus what logrotate wants
to do. Mind you, you will never get log rotation at the time you start
logrotate if you are rotating almost anything else. A big annoyance because
then you don't know which log file you should look at if a problem occurs
around the time logrotate is supposed to run. Frankly, other than lack of
compression (and easy thing to add via a cron job) the xrootd internal log
file rotation is superior simply because it's predictable.

Subject: Re: xrootd 4.1.1 logrotate problem?
Hi,
Has this been understood now? I'm asking because OSG (and probably epel) is
shipping xrootd with -k fifo and logrotate on and this leads to logs being
lost
(it seems like xrootd still does rotation at midnight and then logrotate
kicks
in at 4am and moves the log away ... so this 4-hour interval is all that is
left
of the logs for each day).
