Hello ayushs
About this message: Logmon: backlog buffer overflow
Its because there is a limit in how much lines you can have.
This would be an enhancement request.
As a one workaround, but probably have others, you will need to set the logmon remotely in other robots.
Maybe someone from CA Services can help you further with another workarounds.
Anyway, please open this Idea to increase this logmon limitation.
