Hi Stefan, If you issue a SIGHUP (Hangup signal) to the snmptrapd process, it will re-read its config and also start logging to the rotated (empty) file. You should add this step to the logrotate job.
Watch out for a bug in some older versions (5.6.1.1 notably) where snmptrapd will fail to re-read the config efter 4096 SIGHUPs are received...
