I was poking around in my account's results and noticed a few error messages in the logs, mainly instances of "MacOS Error -43 occured in Mac_Lib.c line 65" and "[CRITICAL]: APP DEBUG: Application caught signal 15."

The WUs have been validated and credited, so I presume none of the exceptions were critical to the results. But are they a cause for concern, regarding either the system's state of health or the project science? Even if they're harmless, I'm curious about what they signify.
