  34 <PRE>After much fiddling, I have finally both removed the 0 nickgroups from my
  35 database and upgraded to services 5.0a24 :)
  36
  37 For anyone affected by this bug, the following steps should remove the
  38 erroneous names and allow you to upgrade to the new version:
  39
  40 1) Make sure you are running version 5.0a23 which has code to not write
  41 nickgroup 0 nicknames to the database file.
  42 2) Identify those nicknames with a nickgroup of 0. I suggest using the
  43 httpd module and the XML download feature. IME this does not display all
  44 nicknames in the database, but nickgroup 0 seemed to always be the first
  45 entry and always list correctly.
  46 3) Drop the nicknames identified as being of nickgroup 0. In my case they
  47 were forbidden nicks so this affected no users. If the nickname is valid,
  48 it is likely not working correctly so although you might want to warn the
  49 users affected, they are likely not using those names anyway.
  50 4) Shutdown services with /os shutdown so it saves the new database.
  51 5) Restart Services 5.0a23, ensuring you do not get any warnings in
  52 services.log for your current database (both on startup and on first write
  53 which you can force with an /os update). Also check that the XML download
  54 does not report any more nickgroup zero entries. If any remain, goto 2 and
  55 repeat until you have cleared them out.
  56 6) Backup your databases. This is important. Even though the startup fails,
  57 I had problems with completely trashed databases when services segfaulted.
  58 7) Install Services 5.0a24 and start them. If they bootup, the nickgroup
  59 bug is now cured. If not, restore your backup and return to version 5.0a23
  60 and goto 2 to find the erroneous entry.
  61
  62 I know at least one other person on the list has problems with this bug, so
  63 HTH.
