  • Migration Impact:
    Can not move ahead with the implementation due to critical TCP transport issues
  • Similar Issues:
    None

Description

TCP transport will transfer at most 2896 bytes per conversation.
Using the supplied configuration...

Used the test harness to transfer over direct, streaming, and length protocols

Failure occurs with length protocol – exceptions from MULE
Failure occurs with streaming protocol – result is mule NullException
Failure occurs with direct protocol – limited-size or NullException during transfer of payload

Changed kernel parameters and increased NIC buffer settings
Set Java to 3 GB of available memory
