I'm tracing a path to my server using tcptraceroute. The server is showing intermittent network availability. It's as if some packets get through fine, others take a long time and some never get there.
Here are two tcptraceroute's to the server. Any idea what would cause such varying output?
1 VLAN host (<VLAN IP>) 0.786 ms 1.250 ms 1.637 ms
2 * * *
3 server host (<serverIP>) 0.632 ms 0.646 ms 0.647 ms
and
1 VLAN host (VLAN IP) 0.848 ms 1.259 ms 1.682 ms

12 * * server host (serverIP) 0.615 ms
The problem was actually KeepAlive was set too high on apache under a production server. Apache's sockets were filled causing what looked like network outages. – kobrien – 2011-06-28T10:57:56.133
