The report in https://help.univention.com/t/smbd-high-cpu-with-no-users/5857 looks like an occurence of https://bugzilla.samba.org/show_bug.cgi?id=12396 It should be checked whether the fix from upstream could be applied to the affected UCS packages.
Yes that patch should apply, it's part of Samba 4.5.4 (errata4.1-4 is at samba 4.5.3 plus security patches). Since the patch only removes the log message I'm not sure that the load would be reduced significantly because it would probably not stop the loop the smbd apparently seems to be stuck in in the forum report. Anyway, I'll consider fixing this along with the next errata4.1-4 samba update.
This issue has been filled against UCS 4.1. The maintenance with bug and security fixes for UCS 4.1 has ended on 5st of April 2018. Customers still on UCS 4.1 are encouraged to update to UCS 4.3. Please contact your partner or Univention for any questions. If this issue still occurs in newer UCS versions, please use "Clone this bug" or simply reopen the issue. In this case please provide detailed information on how this issue is affecting you.
