Issue/Introduction

Found the following errors in ESP Report Server log:
EspReceiver: Received an invalid request length of 369295360.  Rejecting.

Environment

Release : 12.0

Component : ESP REPORT SERVER

Resolution

The logged information tells us that the Report Server's port is in use by some other data source.

The received data is parsed as a standard request format. However the data does not conform to that format. The encoded request length is not valid. Even worse, when the encoded request length is a higher number, the receiving thread could be waiting for some other data to receive.

Check out what could be connecting to your RServer port number or change to a port not being used by any other source.
