If I stop besu soon after startup, I get an exception. Seems like something related to DNSDaemon is not exiting correctly under these circumstances.

Steps to Reproduce

  1. besu
  2. wait until logs show "Ethereum main loop is up" (and maybe wait another 5 seconds)
  3. ctrl-c to stop Besu

Expected behavior: [What you expect to happen]
Expect besu to stop gracefully, as it does if I wait for a minute longer

Graceful stop -
