6027-1756 [E] The TCP connection to IP address ipAddress (socket socketNum) state is unexpected: ca_state=caStateValue unacked=unackedCount rto=rtoValue.

Explanation

An unexpected TCP socket state has been detected, which may lead to data no longer flowing over the connection. The socket state includes a nonzero tcpi_ca_state value, a larger than default retransmission timeout (tcpi_rto) and a nonzero number of currently unacknowledged segments (tcpi_unacked), or a larger than default tcpi_unacked value. All these cases indicate an unexpected TCP socket state, possibly triggered by an outage in the network.

Check network connectivity and whether network packets may have been lost or delayed. Check network interface packet drop statistics.
