Hi, I am using Traffic Server 3.2.0 on Redhat 6.3.
I am using TSNetConnect to create a 2-way communication channel to a separate process. I have noticed that eventually the write side of the channel will stop working although the read side still operates normally. I do not see any error or complete events raised to my continuation. I have checked that the return value from TSIOBufferWrite is as expected and I always re-enable the write continuation after each write. A packet dump is shown below - client is port 45897, server is port 4868. This is taken after ~1 hour of traffic. Normal 2-way data exchange is observed until 17:13:42.461431 when data only comes from the server and TCP acks from the client. This continues until the connection is closed. 17:13:42.395642 IP myhost.4868 > myhost.45897: Flags [P.], seq 8300985:8301053, ack 3873523, win 11343, options [nop,nop,TS val 270071674 ecr 270071673], length 68 17:13:42.396175 IP myhost.45897 > myhost.4868: Flags [P.], seq 3873523:3873558, ack 8301053, win 265, options [nop,nop,TS val 270071674 ecr 270071674], length 35 17:13:42.396855 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301053:8301121, ack 3873558, win 11343, options [nop,nop,TS val 270071675 ecr 270071674], length 68 17:13:42.420982 IP myhost.45897 > myhost.4868: Flags [P.], seq 3873558:3873593, ack 8301121, win 265, options [nop,nop,TS val 270071699 ecr 270071675], length 35 17:13:42.421726 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301121:8301189, ack 3873593, win 11343, options [nop,nop,TS val 270071700 ecr 270071699], length 68 17:13:42.461431 IP myhost.45897 > myhost.4868: Flags [.], ack 8301189, win 265, options [nop,nop,TS val 270071740 ecr 270071700], length 0 17:13:46.375879 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301189:8301222, ack 3873593, win 11343, options [nop,nop,TS val 270075654 ecr 270071740], length 33 17:13:46.375900 IP myhost.45897 > myhost.4868: Flags [.], ack 8301222, win 265, options [nop,nop,TS val 270075654 ecr 270075654], length 0 17:13:46.380377 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301222:8301255, ack 3873593, win 11343, options [nop,nop,TS val 270075659 ecr 270075654], length 33 17:13:46.380395 IP myhost.45897 > myhost.4868: Flags [.], ack 8301255, win 265, options [nop,nop,TS val 270075659 ecr 270075659], length 0 17:13:46.382950 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301255:8301288, ack 3873593, win 11343, options [nop,nop,TS val 270075661 ecr 270075659], length 33 17:13:46.382975 IP myhost.45897 > myhost.4868: Flags [.], ack 8301288, win 265, options [nop,nop,TS val 270075661 ecr 270075661], length 0 17:13:46.385227 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301288:8301321, ack 3873593, win 11343, options [nop,nop,TS val 270075663 ecr 270075661], length 33 17:13:46.385247 IP myhost.45897 > myhost.4868: Flags [.], ack 8301321, win 265, options [nop,nop,TS val 270075663 ecr 270075663], length 0 17:13:46.387441 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301321:8301354, ack 3873593, win 11343, options [nop,nop,TS val 270075666 ecr 270075663], length 33 17:13:46.387459 IP myhost.45897 > myhost.4868: Flags [.], ack 8301354, win 265, options [nop,nop,TS val 270075666 ecr 270075666], length 0 17:13:46.389647 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301354:8301387, ack 3873593, win 11343, options [nop,nop,TS val 270075668 ecr 270075666], length 33 17:13:46.389665 IP myhost.45897 > myhost.4868: Flags [.], ack 8301387, win 265, options [nop,nop,TS val 270075668 ecr 270075668], length 0 17:13:46.391904 IP myhost.4868 > myhost.45897: Flags [P.], seq 8301387:8301420, ack 3873593, win 11343, options [nop,nop,TS val 270075670 ecr 270075668], length 33 17:13:46.391927 IP myhost.45897 > myhost.4868: Flags [.], ack 8301420, win 265, options [nop,nop,TS val 270075670 ecr 270075670], length 0 I would appreciate any help to resolve this issue or any pointers to where I should start looking in the traffic server code.
