Usage: /home/deep/src/httpd-2.0.58/support/.libs/lt-rotatelogs [-l] <logfile>
<rotation time in seconds> [offset minutes from UTC] or <rotation size in
megabytes>
Add this:
TransferLog "|/home/deep/src/httpd-2.0.58/support/.libs/lt-
rotatelogs /some/where 86400"
or
TransferLog "|/home/deep/src/httpd-2.0.58/support/.libs/lt-
rotatelogs /some/where 5M"
to httpd.conf. The generated name will be /some/where.nnnn where nnnn is the
system time at which the log nominally starts (N.B. if using a rotation time,
the time will always be a multiple of the rotation time, so you can synchronize
cron scripts with it). At the end of each rotation time or when the file size
is reached a new log is started.

------- Additional Comments From jorton@redhat.com 2006-05-03 13:31 -------
You're running valgrind, the *uninstalled* rotatelogs program, which is actually
a libtool wrapper script. Run valgrind on the *installed* rotatelogs program,
and you might get interesting results. But since rotatelogs does not use
malloc/free directly, only pools, this is unlikely too.
