Problem with Watched Folder endpoint

Hi,

We have a problem with a watched folder endpoint. The watched folder is set in a directory in a linux server. The directory then is mapped to a windows directory where files arrive from time to time. Everything works fine until the watched folder service stops for no particular reason. After that we need to restart the service from the admin UI console.

I found in another post something related to the MySql database losing connection with livecycle after some inactivity, but I'm not sure if this is our case or even how to solve the problem.

Here's what we found in the log
