TCP: Possible SYN flooding on port 80.
sounds sinister but may not mean anything useful at all if I'm correctly interpreting
no warning in any logs at all, except with the usual
web10 kernel: possible SYN flooding on port 80
from Apache mailing list.
I tried this exact search
"Possible SYN flooding" "port 80" site:.apache.org
That gets you the archived mailing lists. Have fun disentangling the threads; I couldn't figure out how to do it except by brute force. Helps that the question I was trying to follow was posted on 30 September, so all the answers came in on 1 October, putting them in a whole new segment of the archives.
