Does anybody be aware of concept of the data message "all endpoints are disconnected, detected by connect check (1), cping (), send ()"

This happens with a few regularity during my mod_jk log, however i aren't able to find details about whether this can be a problem, or simply something to disregard.

Which means that tomcat has shut lower the socket because of the soTimeout parameter from the AJP connector. mod_jk will reunite next, therefore this really is basically an [info] message. When the reunite fails, an [error] is going to be drenched. Making this entirely harmless.
