[Warning] dropping a split packet from client

Hello, this warning is related to sscanf, correct?

Is there any way to resolve this? I tried some things but it didn't work.

 00.000.000.000:0000 requests connection cookie.
  incoming connection: 00.000.000.000:0000 id: 0

This warning appeared on the host, I had no opportunity to test on the PC.

Help me, pls.
