Description: 

(event [0x03e00014])

Environment

Release : 21.2

Cause

This is due to the limitation from Operating System on environmental variables 

Resolution

The Event Size limit is coming from the Windows environment variables.

The event is passed from Notifier to the Setscript as an ENV variable.

As per Microsoft the limit is set to 32767 chars.

As the limitation is on Operating System side hence nothing much can be done from Application side.
