Unable to find response container for <UUID>

I see this error in a Liferay log file:

INFO  [Incoming-1,liferay-channel-control,FOO03-38099][ClusterRequestReceiver:250]
Unable to find response container for b62ef2ea-00c6-11e8-ba89-0ed5f89f718b

When searching the Internet, there are only 7 results, mostly source code, plus 2 Liferay issues that seem to ignore the message.

My question:

  • What does this message mean really?
  • Can I safely ignore it?
Solution

  • The context you're describing doesn't contain a lot of hints as to when this is occuring. Due to the location of the code deep within clustering, it's quite abstract.

    Based on the fact that

    • it's not an ERROR but an INFO
    • The comment on LPS-56376: "Has no real impact to system other than info level log messages stating: Unable to find response container for:... from ClusterRequestReceiver"
    • The title of LPS-56376: "ClusterableAdvice is not flagging methods that return void as "fire and forget""

    and without deeper analysis, I'd ignore this message.
