Hi, Here is my problem. I've a java application using Spring Integration to send data to Splunk (with TCP). inputs.conf : [tcp://1234] connection_host = dns source = TracerSource sourcetype = TracerSourceType queueSize=1GB spring-context.xml ... < int-ip:tcp-connection-factory id="client" type="client" host="${tcp.host.name}" port="${tcp.port}" using-nio="true" using-direct-buffers="true" single-use="true" so-timeout="1000" /> < int-ip:tcp-outbound-channel-adapter id="outboundClient" channel="jmsOutputChannel" connection-factory="client" /> ... Many times I've these error messages and the java application stops. ... TcpSendingMessageHandler [ERROR] Error creating SocketWriter java.net.SocketException: No buffer space available (maximum connections reached?): connect at sun.nio.ch.Net.connect(Native Method) ... DefaultMessageListenerContainer [WARN] Execution of JMS message listener failed, and no ErrorHandler has been set. org.springframework.integration.mapping.MessageMappingException: Failed to create connection ... Do you have any explanation ? What is the best solution/configuration to manage many messages ? (1000 msgs/min - size of each msg : 1Ko to 10Ko) Thanks in advance. ... View more
