ATS 6.2 Forward Proxy some site has intermitted issue to load
Hey Guys,
I’m pretty new in ATS, I have setup ATS 6.2 as a forward proxy, compiled from source, and running on RedHat 7.2, the reverse proxy has been disabled.
I use Firefox as client to test it, and for some reason, I have issues to load some site for the 1st time, a refresh will fix the issue, but it can be re-produce from time to time also generate the following traffic.out logs:
Nov 7 04:13:31 maude-proxy-01 traffic_server[8669]: {0x2aaab6a29700} ERROR: <HttpSM.cc:1159 (state_raw_http_server_open)> [HttpSM::state_raw_http_server_open] event: EVENT_INTERVAL state: 0 server_entry: (nil)

Here’s the picture when it’s happening, the get js should return 304, but somehow it hangs there.
and no coredump generated, the traffic_server are not crashed, so far I only have the log, any suggestion to troubleshooting this issue will be very helpful.
Thanks,
Di Li

Your not the only one, we see that sometimes connections to trafficserver
aren't ack'd but we're not sure why. Not every connection has the issue,
and subsequent connections will be acked, so seems to be some interaction
with the kernel that is not well understood.

Hey Guys,
I'm pretty new in ATS, I have setup ATS 6.2 as a forward proxy, compiled from source, and running on RedHat 7.2, the reverse proxy has been disabled.
I use Firefox as client to test it, and for some reason, I have issues to load some site for the 1st time, a refresh will fix the issue, but it can be re-produce from time to time also generate the following traffic.out logs:
