Hello,
I'm having trouble with some connections active for hours on HAProxy
(1.5.2) but not doing anything.
Timeouts are defined like this :
timeout connect 5s
timeout http-keep-alive 5s
timeout http-request 10s
timeout queue 30s
timeout client 25s
timeout server 1m
timeout tarpit 1m
If I look at a specific connection and tcpdump it, I see absolutely no
trafic, so I was expecting HAProxy to close the connection when either
'timeout client' or 'timeout tarpit' is elapsed.
"show sess" on such connection shows output like this :
0x2046920: [13/Oct/2014:15:23:20.164269] id=1125543 proto=tcpv4

I mentioned tarpit because there is a high chance connection was tarpitted.
In the output above, I can see task state 0x08. Where could I find what
this is ? If I take a look at stream_interface.h, there are several values
mapped to 0x08...
Any help would be appreciated :)
