I have the same problem. Here is what I did Context:
- launchctl limit maxfiles --> maxfiles 256 unlimited 256 is by far not enough for my application Actions:
- more /Library/LaunchDaemons/limit.maxfiles.plist to examine the /Library/LaunchDaemons/limit.maxfiles.plist file, there the limits were 20000 20000
- reboot with +R (recovery mode)
- launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist to modify permanently the 2 limits
- reboot normally
At that point, my problem was solved. But
- I did not re-enable crsutil (I'll try when I'll have made up for the time lost on this Apple bug, but as I am the sole user of this machine and that type of modification can only be done in recovery mode, I feel quite safe to stay this way...)
- there is a curious discrepancy: ulimit -> unlimited ulimit -Sn 20000 ulimit -Hn 20000
I hope this can help.
