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