when a sockjs heartbeat fails with a
SockJsTransportFailureException
, it seems the exception just bubbles up and is logged at
ERROR
level.
however, looks like this exception is also thrown if a client just goes away, which does not qualify as an error condition but should rather be expected.
https://github.com/spring-projects/spring-framework/blob/v4.3.7.RELEASE/spring-websocket/src/main/java/org/springframework/web/socket/sockjs/transport/session/AbstractSockJsSession.java#L255
https://github.com/spring-projects/spring-framework/blob/v4.3.7.RELEASE/spring-websocket/src/main/java/org/springframework/web/socket/sockjs/transport/session/AbstractSockJsSession.java#L339
would be nice if this condition is just logged at
DEBUG
not causing that much noise.
the reference url shows a corresponding stackoverflow question. that one is using the tomcat APR connector, it seems but we also get such error logs frequently with the tomcat NIO connector, then it looks like:
