I've copy pasted gRPC server from gRPC helloworld example.
It starts listening for RPC in specified port, but when I call the RPC with a copy pasted client, it crashes with "Aborted (core dumped)" and in client side I get error message "Endpoint read failed".
I tried debugging this by including some output statements in RPC function implementation, but the execution never reaches the point.
There are no other error messages, is there some flag to make the failure more verbose for debugging?
Besides GRPC_VERBOSITY as mentioned above, you should also set GRPC_TRACE to something like http,secure_endpoint and use a debug build. For a complete list of options: https://github.com/grpc/grpc/blob/master/doc/environment_variables.md
IIUC the build succeeds, so I don't think this question needs the #bazel tag.
Looks like you can set the GRPC_VERBOSITY environment variable to values "DEBUG", "INFO", or "ERROR"(https://github.com/grpc/grpc/blob/fead0879460da1a7990d43472f770bb4fe8145f6/src/core/lib/support/log.cc#L68) in order to control logging.
