Lösung zum Fehler: Process crashed: opendirectoryd. Too many corpses being created.

Nach dem 10.13.3 Update hatten wir vermehrt Probleme mit Kundenrechnern, die nicht bis zum User-Login gebootet haben. Gestartet im Verbose-Mode konnte man sehen, dass die Rechner an folgender Stelle hingen:

(161) Process crashed: opendirectoryd. Too many corpses being created.
(162) Process crashed: opendirectoryd. Too many corpses being created.
(163) Process crashed: opendirectoryd. Too many corpses being created.
(164) Process crashed: opendirectoryd. Too many corpses being created.
(165) Process crashed: opendirectoryd. Too many corpses being created.

Das ist jetzt ein bei Apple bekanntes Problem (wir haben es dort eskaliert) und es wird mit dem nächsten Update behoben werden.

Hier die passende Lösung von Apple dazu (können wir aber erst nächste Woche testen):

If you want to remove all users (without removing home folders)
If you suspect that the local database which stores user accounts is damaged, follow the steps for the version of OS X you're using below. These steps remove all user accounts without removing their related Home folders, and make Setup Assistant open again.

Start up in Single-User Mode by holding Command-S when you turn on the computer. Wait until white text appears.
At the prompt, type each of these commands on single line as they appear below, and press Return at the end of each line.

mount -uw /
cd /var/db
mv dslocal dslocal.old
mkdir -p dslocal/nodes
cp -Rp /System/Library/DirectoryServices/DefaultLocalDB/Default dslocal/nodes/
rm .AppleSetupDone
reboot

Once the computer restarts, complete Setup Assistant to create the administrator user account again. When creating the account, the short name entered into the Account Name field should match the name of the user's home folder in /Users, so that the new user will use the existing home folder.
After Setup Assistant, open Terminal and type this command:

sudo chown -R username:staff /Users/username

Note: There is a space before "/Users/". Replace "username" with the user's short name that was entered in Account Name field during the previous step.

If there was more than user on the computer, use the Accounts pane of System Preferences to re-create any remaining users. When creating each account, the short name entered into the Account Name field should match the name of that user's home folder in /Users, so that the new user will use the existing home folder.
