Hi all,
I am using grpc java as a grpc client to connect to a remote GRPC
server. The RPC is a server streaming RPC.
I first build the channel (have not provided customized executor), and then
invoke the RPC.
Scenario:
1. I have several destination servers where i have to connect.
2. for one destination, the same RPC can be invoked multiple times (with
different parameters)
3. The RPC is server streaming RPC.
What did I do:
1. I created one ManagedChannel(have not provided customized executor) for
each destination server.
2. On the same ManagedChannel, i invoke multiple RPCs as and when required,
and the RPCs keeps running (server keeps on streaming) until user stops the
operation.
Problem:
After few hours, i see there are many threads(in several hundreds) which
are spawn by the application and it keeps on increasing with time.
PS: I don't have a thread dump. The thread leak was identified by some
external tool in production environment
