--timeout is not respected

tcurl -p localhost:44390 foo --timeout 500000 --health
NOT OK
TchannelConnectionTimeoutError: connection timed out after 2001ms (limit was 2000ms)

@kriskowal have you seen this before?

connection timeout is different and not configurable.

There are two timeouts.

• init handshake of the tchannel protocol must finished in 2 seconds (aka timeout for init response)
• rpc request must finish within --timeout time, ( aka timeout for call response ).

If the init handshake times out that generally means that the TCP connection was opened but the remote side did not speak the tchannel protocol ( HTTP server ? )

Other reasons why the init handshake fails is

• a fatal exception in the remote server, it will never respond
• a bug in the tchannel server library
• trying to make a request to a 100% CPU process

The server is speaking tchannel and it's a local process, which means that it's either

• a bug on server side (possible but unlikely since the server is running fine)
  or
• make request to 100% CPU process: could you clarify a bit on this? 100% means 1 core or all cores on the server?

@ctrlhxj You can try using tcap to help diagnose what's going on.

If you really want to have a much higher timeout for a connection, you can also try using yab which uses the specified timeout for connecting as well as the request.
