We had another similar issue today.
Baseline applied to client. Client got about midway and then just stopped. No additional logging to the client log for over 35 minutes.
Called support, looked at client log and stated it looked like UDP was being blocked between client and server. Had me send blank action. As suspected action never ran and client did not log anything to client log. Client eventually greyed out in console. Wanted me to reinstall client to make sure it wasn’t corrupt. I declined - this is not an acceptable solution for a product that is supposed to be our End Point Security agent.
Support continued to say it must be UDP. So I right clicked on the greyed out client and chose “Send Refresh”. Client immediately woke up and went merrily on it’s way, completing the action.
We’ve also resolved this issue in the past with a restart of the client. To us, this definitely looks like a client agent issue. There seems to be some instability that just can’t be tracked down.
