Do you have logger installed? You coupled pipe your CustomLog into logger which will facilitate Apache writing to syslog, in lieu of directly writing the file. After some tweaking this should let you use the systems standard log rotation schema.
Something like: CustomLog "| logger -t httpd -p local.info" Cheers, m On Aug 3, 2013, at 19:11, Frank Leonhardt <freebsd-...@fjl.co.uk> wrote: > The answer isn't (AFAIK) newsyslog > > As a one-off, I need to archive an old log file - say httpd-access.log - > while its still open.
