Backup weak variable error

I am getting this error in my system.log:

Sep 27 18:31:49 Laptop backupd[12963]: objc[12963]: __weak variable at 0x7f86fd45afb0 holds 0x7f86fd450003 instead of 0x7f86fd451900. This is probably incorrect use of objc_storeWeak() and objc_loadWeak(). Break on objc_weak_error to debug.

The Time Machine backup appears to be working correctly, but how do I determine if it is? There is not a lot in logs that tell me anything. What does this error message mean. I am seeing this on 2 different machines.

MacBook Air, macOS Sierra (10.12)

theperlarsen - thanks for the helpfull suggestion and code for terminal.

However, my errors seems to be somewhat diffrent, as it seems to refer to something with a missing port creation. Please se below.

Suggestions are much appreciated.

Thanks.

I have the same log messages caused by Path Finder and constantly occurring every couple of minutes.
