Hello Kay, graylog2-server is running as root, on CentOS 6 minimal that does not have additional limits.
I've noticed that this exception is shown only with TCP input..so there may be TCP limitation. I haven't tweaked TCP since we use TCP only for Keepalived HTTP checks, and UDP for logs (GELF input). Both TCP and UDP socket are on same port (12001). Could this cause issue with receiveBufferSize on graylog2-server?
