well, being the big logfile i just grepped for Meter ..
but i found the problem and, as you said, the "metering" script of
cms.perf had bad ownership and no execution rights for others.
i was wondering, is it possible to have an "internal" version of
cms.perf with the reporting code being included in the actual binary?
(to be used like cms.perf pgm internal) or as fallback if pgm is invalid?
and a better error handling for the server? (it should not break just
because an improper cms.perf declaration)
Thank you!
