This message comes from the server (origin) session closing code:
void
HttpServerSession::do_io_close(int alerrno)
...
// Check to see if we are limiting the number of connections
// per host
if (enable_origin_connection_limiting == true) {
if (connection_count->getCount(server_ip) > 0) {
connection_count->incrementCount(server_ip, -1);
char addrbuf[INET6_ADDRSTRLEN];
Debug("http_ss", "[%" PRId64 "] connection closed, ip: %s, count: %u",
con_id,
ats_ip_ntop(&server_ip.sa, addrbuf, sizeof(addrbuf)),
connection_count->getCount(server_ip));
} else {
Error("[%" PRId64 "] number of connections should be greater than zero:
%u",
con_id, connection_count->getCount(server_ip));
}
}
So you are limiting the number of connections to an origin, which means that we
have to track the connection counts. This code is decrementing the connection
count, but it is already zero. The error message seems to have the intention of
telling you that it would have decremented the count below zero, so there's
probably a counting bug somewhere.
