Hi,
These are internal to Tomcat. It is likely holding references to the
mentioned Ignite objects and cannot release these references causing a
memory leak.
These messages can be safely ignored providing Tomcat is not prevented from
shutting down. As they occur during shutdown, any memory leaks will cease
once the process has ended.
Please see Tomcat documentation for more on these memory leaks.
