Why do I keep getting "INFO TailReader - File descriptor cache is full (100), trimming..." in the splunkd.log on a heavy forwarder?

Hello

Getting what I would think is an error, but its listed as info level, not sure what it means

INFO  TailReader - File descriptor cache is full (100), trimming...

Can someone tell me what this message means please?
Thanks

the forwarder is tailing up to 100 files (filed descriptors open at the same time), and explains that it has more than 100 files to monitor, so it will close open files to be able to open and scan the other files.

It's an INFO event, nothing much to worry about.

Cool, thanks for the explanation. I appreciate it
