Can anyone help me find the root cause for timeout here ? Increasing the timeout value may not provide a solution here, as this issue is seen while downloading a 30mb file and as we download bigger files say for example a 1Gb file, more delays might be seen.
Here are the http logs seen for this : DEBUG: <HttpSM.cc:2638 (main_handler)> (http) [2] [HttpSM::main_handler, VC_EVENT_INACTIVITY_TIMEOUT] DEBUG: <HttpSM.cc:883 (state_watch_for_client_abort)> (http) [2] [&HttpSM::state_watch_for_client_abort, V C_EVENT_INACTIVITY_TIMEOUT] DEBUG: <HttpSM.cc:923 (state_watch_for_client_abort)> (http) [2] [watch_for_client_abort] forwarding event VC_EVENT_INACTIVITY_TIMEOUT to tunnel DEBUG: <HttpTunnel.cc:1354 (consumer_handler)> (http_tunnel) [2] consumer_handler [user agent VC_EVENT_INA CTIVITY_TIMEOUT] DEBUG: <HttpSM.cc:3195 (tunnel_handler_ua)> (http) [2] [&HttpSM::tunnel_handler_ua, VC_EVENT_INACTIVITY_TI MEOUT] DEBUG: <Http1ClientSession.cc:287 (do_io_close)> (http_cs) [2] session closed On Sat, Jun 17, 2017 at 7:11 PM, Gaurav Bansal <[email protected]> wrote: > Hi all, > > We are writing a transform plugin where we get the data from server, > perform some checks on the data & write the data back to the client using > following api : > TSVIO *TSVConnWrite*(TSVConn connp, TSCont contp, TSIOBufferReader > readerp, int64_t nbytes) > > Here, I am seeing the issue of *VC_EVENT_INACTIVITY_TIMEOUT*.
