Hello,
Im new to Akka/Akka Remoting..
We need to send large messages in the order 500-600MB. After viewing and
checking some mailer post I found that I have to change Akka Remote netty
tcp settings which I did and my application.conf has the following...
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
netty.tcp {
hostname = "<ip address of host>"
port = 2553
maximum-frame-size = 524288000
send-buffer-size= 500000000
receive-buffer-size=500000000
}
}
I create a client and remote server app using akka-remoting. Using
protobuff message serialization -- a client sends a large message to server
and the server acknowledges with the timestamp when it received after
deserialized the same.
With above settings things work fine for messages upto 200MB. When I try
slightly large message 250MB.. The server shows the following ..
---
[INFO] [08/05/2014 23:41:39.302]
[RemoteNodeApp-akka.remote.default-remote-dispatcher-4]
[akka.tcp://RemoteNodeApp@<remote-ip>:2552/system/transports/akkaprotocolmanager.tcp0/akkaProtocol-tcp%3A%2F%2FRemoteNodeApp%40<remote_ip>%3A36922-1]
No response from remote. Handshake timed out or transport failure detector
triggered.
---
and the client shows the following
[WARN] [08/05/2014 23:41:39.326]
[LocalNodeApp-akka.remote.default-remote-dispatcher-6]
[akka.tcp://LocalNodeApp@<client_ip>:2553/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FRemoteNodeApp%4010.194.188.97%3A2552-0]
Association with remote system [akka.tcp://RemoteNodeApp@<server_ip>:2552]
has failed, address is now gated for [5000] ms. Reason is: [Disassociated].
and the message is not sent at all.. Any idea what else is missing?
BTW -- in the above I don't see any OOM errors or anything and the
client/remote app are still up and running.
thx
