 Description   

Current limit is 1000. Sometimes Proxies/Frontend are failing with TCP/10051 port due to the intensive processing of the data from Proxies by already allocated 1000 trappers.

With customised sources and 2500 trappers:

Required limit: 5000. Increasing trappers reduces Trapper port availability problem.
