StatusRuntimeException with gRPC stream: Channel closed

[mur...@akruta.com]

Hi all,

I am trying to use multiple grpc bidirectional streams in the same service between a client and server. And every now and then I get the following error:

```

 io.grpc.StatusRuntimeException: CANCELLED: cancelled before receiving half close

        at io.grpc.Status.asRuntimeException(Status.java:517)

```

did anyone else face this issue?

any pointers would be really appreciated.

Thanks,

This error occurs on the server side.

Also, what is the default timelimit for an rpc call?

[Carl Mastrangelo]

Cancellation is usually done by your application code, unless there is a proxy in the path.  There is no default time limit, and RPCs will never time out normally.   You can add one by setting a deadline on the stub.    Deadlines will fail with a DEADLINE_EXCEEDED error code, rather than a CANCELED.
