After the cluster has been up for a longish period (> a day or so), and only then, I'm seeing:
[2014-07-20 00:00:00,708][ERROR][akka.remote.EndpointWriter] [akka.tcp://[email protected]:ZZZZ/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FXXXX%40YYYY%3AZZZZ-16/endpointWriter] Transient association error (association remains live) akka.remote.OversizedPayloadException: Discarding oversized payload sent to Actor[akka.tcp://XXXX@YYYY:ZZZZ/]: max allowed size 128000 bytes, actual size of encoded class akka.actor.ActorSelectionMessage was 147704 bytes. logged every second, for message sends to different cluster members. This is on a 21 node cluster, however there is one peculiarity that some some processes join the cluster via cron jobs (2 of them every minute) and exit shortly. Despite this OversizedPayloadException logging, the cluster seems to be functioning normally otherwise. New members are joining and leaving. I just shutdown the cluster singleton and failover happened smoothly. The number of bytes on that actor selection message keeps growing, BTW. It had gone from 147K to 178K in about 6 hours. I understand there is a setting for the payload size limit, " akka.remote.netty.tcp.maximum-frame-size", but before bumping that I'd like to understand what is going on here. Could this be a consequence of the fact that akka cluster does not perform vector clock pruning, and I have nodes constantly joining and leaving? If so, it's strange that the cluster can keep functioning despite what may be failed gossip sends? I don't think this is anything at the application-level, the messages sent using selections are quite small. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
