Title:
  smbd spawns hundreds/thousands of processes

Status in “samba” package in Ubuntu:
  New

Bug description:
  Sometime in the past week, my server has started spawning hundreds (or
  even thousands) of smbd processes, driving the load average through
  the roof.  Once every minute or so, it appears to start a new one.

  Output from ubuntu-bug is attached.
