Problem with Watched Folder endpoint

Question

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

Otherwise, I'll start with Endpoint on a fresh machine install it and it works great pulling down the policies. But the ZCM doesn't seem to pull down the policies correctly?
Just wondering if this was known problem or is there something I am not doing correctly...
Thanks

This is issue that you are seeing is just for the client, correct? The ZESM server and ZCM server are on separate machines, correct?
