title: ZMQ: Assertion Failed with JZMQ
body: <p>My Java server runs pretty well for a while with JZMQ.
  And suddenly it got Assertion failed: check () (msg.cpp:220)</p>
  
  <p>It cannot be caught in JAVA. And the java process is down itself.
  It seems like Cpp issue in JNI</p>
  
  <p>May I know if any one know what happens in this exception?</p>
  
  <p>Thanks</p>
