It is a jack2 message and /usually/ indicates a Xrun: A client could not
be activated in time before the current cycle ended. (it is an Xrun if
you run jackd in synchroneous mode and may be an Xrun in async mode.)

quoting Stephane Letz - jack-dev on 15.07.2011:

  They are still not "strict XRun": in asynchronous mode XRuns are
  detected by the server which just checks that all clients have be run
  previous cycle. It then print something like:
  JackEngine::XRun : client = XXX was not run: state = 2

Note the Xrun message is produced by the server (and ends up in
~/.log/jack/jackdbus.log - or on the jackd's stderr).
The JackActivationCount message is produced by libjack and printed by
the client application. Since jackd 1.9.8 the latter should only be
printed in verbose mode.
