tarpc freezes/shuts off after a few days of uptime #538
Description
When tarpc is running for a longer time, after a while, each call with an existing client return the connection to the server was already shutdown, on all clients and new clients can't connect anymore, only after a server restart.
I don't know what causes this, but it generally happens after a few days of server uptime. I use this purely internally, not exposing the port beyond the machine, only to communicate from a linux host into multiple windows VM's.
This is the server impl:
async fn start_tarpc_server() -> Result<()> {
let mut listener = tarpc::serde_transport::tcp::listen(
(
IpAddr::V4(Ipv4Addr::UNSPECIFIED),
env::var("NODE_PORT")?.parse()?,
),
Json::default,
)
.await?;
info!("Listening on port {}", listener.local_addr().port());
listener.config_mut().max_frame_length(usize::MAX);
listener
// Ignore accept errors.
.filter_map(|r| future::ready(r.ok()))
.map(server::BaseChannel::with_defaults)
.map(|channel| {
let server = SupervisorServer(channel.transport().peer_addr().unwrap());
channel.execute(server.serve()).for_each(spawn)
})
.buffer_unordered(usize::MAX)
.for_each(|_| async {})
.await;
Ok(())
}I'm also trying to get more metrics/logging into this to monitor how many are connected, etc. but that's still running and I have to wait until it freezes again.
