Hello all,

I have an embedded hornetq server in my webapp, but when I stop my webapp (and I also stop correctly my hornetq server stop log of hornetq is correctly loggue ...) I have
a thread in waiting state "HornetQ-client-factory-pinger-threads-299804241-1472872240" which stay in my JVM ...

how I can shutdown this thread at the stop of HornetQ ?

I also have done a heapdump with several instances classes stay in live, how I can found what it keep these reference ? (I have try to found with jvisualvm or yourkit
but I am not very good with these tools).

Do you have an idea ?

Best regards an thank you

Try Eclipse MAT and take a look at the Dominator tree view tracing the GC roots of the objects that you know that don't have to be there.
