      I'm having the same issue. I can probably get this done during a scheduled outage on the jenkins master, but that's really invasive. Is there any way to call a function via groovy to reset and clear the content?

          This is a groovy script I created to clean up the Xvnc display numbers without stopping jenkins. But it might also clean up numbers of still running jobs.

          https://github.com/sdiepend/jenkins-monitoring/blob/master/cleanXvncDisplayNumbers.groovy

          import jenkins.*
import jenkins.model.Jenkins


Jenkins jenkins = Jenkins.getActiveInstance();
xvncDescriptor = jenkins.getDescriptorByType(hudson.plugins.xvnc.Xvnc.DescriptorImpl.class)


xvncDescriptor.allocators.each {
  allocator = it.value
  // collect is used to make sure numAlloc is an entire new list and not just a reference to the same list object, otherwise you'll get a
  // concurrentmodification exception
  numAlloc = allocator.allocatedNumbers.collect()


  numAlloc.each {
    allocator.allocatedNumbers.remove(it)
  }
}
