DLO Agent terminates after getting deadlock errors

Problem

The Desktop and Laptop Option (DLO) Agent does not launch on multiple client machines. The backup for those client machines does not happen. The DLOClient Log shows that the Agent is terminated.
 

Error Message

The DLO Debug shows the following error :

Cause

 

Multiple clients requesting to get the ActiveSLPath updated in DB results in a deadlock. Due to this, the client agent terminates.

Solution

Workaround :
Launch the DLO Agent manually and the backup should start to run.
