This situation seems to be happening because `channelInactive` is called when the underlying TCP closes, and it is taking long to time out in the case the other end of the connection is gone. I see here in `PerChannelBookieClient`: https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/proto/PerChannelBookieClient.java#L567 that we are setting `SO_KEEPALIVE`, but the default configuration is such that the first probe is really long after the last packet sent. One option might be to configure the related options, like `TCP_KEEPIDLE`, `TCP_KEEPINTVL`, and `TCP_KEEPCNT`. `TCP_USER_TIMEOUT` is another option. I'm a bit puzzled about the 15-minute value interval, though. I see references to docker swarm issues, but I can't map to the scenario we have. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
