ControlLogix attempted to read a ControlLogix Optimized packet

ControlLogix attempted to read a ControlLogix Optimized packet [4c12928] that doesn't exist, reinitializing the packet. [10100cc]

Possible solution

The connection timeout and the controller time are different, and RSLinx Classic attempted to read an optimized packet on a connection that was dropped. We can read packets on one connection that was created on another connection.
