launchd @ 100% CPU or more after update to 10.15.4

I updated my Mac mini (2018) to 10.15.4 today, and now launchd is consuming 100% of CPU according to Activity Monitor. Console shows that it is continuously failing to launch diskutil, as it is searching in /usr/sbin/diskutil, and apparently it no longer has access to that location. /usr/sbin/diskutil is certainly there, has read and execute permissions, and I can manually start Disk Utilities from Finder. How do I fix this?



% ls -l /usr/sbin/diskutil
-rwxr-xr-x  1 root  wheel  532080 Mar 17 08:42 /usr/sbin/diskutil


From console:

After further investigation, the problem is directly related to my Drobo 8D. If the Drobo 8D is detached from the system, then the messages stop. If I reattach the Drobo 8D (via TB3), then the messages start up again. I have cases open with both Apple Support and Drobo Support. This seemed to start after upgrading to macOS 10.15.4, but perhaps I just didn't notice it before.


I do have other external storage, both APFS, as well as Mac OS Extended Journaled (same as Drobo 8D volumes), but the issue does not occur with the other devices.
