Title:
  8.04 winbindd crash in ads_do_paged_search_args

Status in “samba” package in Ubuntu:
  Fix Released
Status in “samba” package in Debian:
  Fix Released

Bug description:
  Binary package hint: samba

  I'm having an issue with winbind. Every few days (3-8 so far with 4
  events) it seems winbindd crashes and restarts. I've checked to see if
  any of my cron activities are causing the problem by running them by
  hand. I have a log entry that occurs 6 minutes before the failure in
  /var/log/samba/winbindd.log. It also appears relevant from the
  information in the stack trace.

  /var/log/samba/winbindd.log:
  [2008/06/28 05:44:19, 1] nsswitch/winbindd_util.c:trustdom_recv(229)
    Could not receive trustdoms
