Miroslav Novak updated WFLY-9943:
---------------------------------
    Description: 
Sometimes happens that WF12 process does not exit when :shutdown CLI operation called and hangs indefinitely. This happens only RHEL 6 (32/64 bit) with IBM SDK8.

Calling kill -3 does not create any javacore dump and only output could be gathered from pstack (attached). It indicates that JVM shutdown thread is hanging on:
