This is just an informative message. It is not a problem with the system. The message is informing the system administrator that a remote system is not able to communicate correctly with the system in question. It is a problem on the remote system. It indicates that the system in question has received packets with incorrect TCP information. It is caused by a remote host, or intermediate firewall/NAT getting TCP behavior incorrectly. In the usual cases, the only likely impact is a little performance drop on the connection.

From /usr/src/linux/net/ipv4/tcp_timer.c:

/* Receiver dastardly shrinks window. Our retransmits
 * become zero probes, but we should not timeout this
 * connection. If the socket is an orphan, time it out,
 * we cannot allow such beasts to hang infinitely.
 */

So it appears that someone is running some sort of \"tar-pit\" system that is designed to keep sockets in a bad state and run you out of kernel memory.
