logfile incorrectly zipping

user reported:

We have noticed that on Thursday(morning) a logfile for Thursday became zipped, incorrectly. Haven’t seen before, didn’t happen since then, I had not found any evidence that this was a justified behaviour… except if the find unix command that our housekeeper uses with the agemin defined with a constant “+” prefixed parameter can result in such a bad timing that exclusion of the logfile didn’t happen as the logfile got modified just at that time(or roughly a min ago if mmin +0) but when a few milisecs later the match for deletion happens the logfile was”old enough” to fulfil that criteria - leaving you with effectively no tplog for the day.
