How can I fix this CODESIGNING error?
I have observed the same error when deploying my own signed apps. It appears that if you mv/cp a new binary over an existing signed one, the kernel does not keep track of this very well and starts generating these errors.
I have found that this does not occur if the new binary is installed as part of a package, or if the original binary is deleted first and then the new binary put in place.
Additionally once in this situation, a reboot fixes the issue, presumably as the kernel codesigning table is stored in memory. I appreciate rebooting may not be an option in a server environment.
