No you don't have to restart Kannel. You just have to instruct newsyslog to send SIGHUP to Kannel when it rotates the logs.
ah okay, i just passed --pid-file /var/run/kannel.pid and then included this in newsyslog.conf. from man newsyslog:
pid_fileThis optional field specifies a file containing the PID of a process to send a signal (usually SIGHUP) to in-stead of /var/run/syslog.pid.
just sending this back to the list for posterity :) cheers iain
