Description

When Multiple File is set as Tailing Mode, TailFile tries to recover the state every time it is triggered, as if it were recovering from a restart. In this way, it opens a new reader every time for every file and it never closes them.

This situation can easily be diagnosticated running lsof: the number of open handles keep increasing for every TailFile trigger.
