What does the "TCP: time wait bucket table overflow" message mean or what does the TCPTimeWaitOverflow counter indicate?
Issue
-
On a system handling lots of TCP connections, the logs are filled with these messages:
kernel: TCP: time wait bucket table overflow
-
In RHEL7, there is no log message but
netstat -s
shows aTCPTimeWaitOverflow
counter incrementing.
