ReportCrash spamming "Failed to start process notifications for pid"

Hi! This is my first post, I apologize in advance for any faux pas.

Primary issue: I'm getting periodic high ReportCrash CPU usage.

I opened up Console.app and find out that ReportCrash is spamming this error message: "Failed to start process notifications for pid #" ReportCrash seems to be showing that the error is from CoreSymbolication.

The pid # in the error messages are in increasing order, and none of the pid number can actually be found in Activity Monitor CPU tab. They looks like this:

The machine is an Early-2015 13-inch MacBook Pro; 3.1 GHz Intel i7; 16 GB DDR3. I'm running macOS High Sierra ver 10.13.5

I'm thinking about force-quitting coresymbolicationd, but thinking it's a private framework and probably kernel related I haven't tried that.

Anyone has any ideas?

Thanks!
