Telegraf stops logging after logfile is recreated

telegraf

#1

Running Telegraf 1.6 on Redhat Linux, using the logparser plugin.
Every night certain logfiles are renamed and new logs created (e.g. mv event.log event.log-2018-03-12; touch event.log)
Our telegraf is watching these logs, and when they get renamed, telegraf stops collecting updates - maybe telegraf is holding on the the file handle… I have tried watch_method = poll AND inotify.
Note that on rare occasions, the logging continues. Any clues on what is happening and/or how to resolve the problem?
UPDATE:
This version has the problem:
Telegraf v1.6.0~aa2f9d7 (git: derrley/2099-GCP-Stackdriver aa2f9d7)
This version works fine (using pull):
Telegraf v1.5.1 (git: release-1.5 0605af7c)
