ERROR

Description

This message occurs when an overflow is detected in the TCP socket send buffer. The TCP socket send buffer can hold a maximum of INT_MAX (2147483647) bytes.

Corrective Action

Excessive unacknowledged data in the socket send buffer is commonly due to an overloaded client that is extremely slow to send TCP acknowledgments or completely stops doing so. Examine the client and take actions to address the client behavior.

Parameters

server_address (STRING): IP address of the server.
