Well, it’s too bad that 26T didn’t respond to Linc’s request for a dump as he was by far the smartest troubleshooter on the forum until he suddenly bowed out back then.
If I had to guess, I’d have to say that the problem is with a developer who has miscoded the use of the suggestd process which causes the process to quit without delivering the desired results. So it’s only actually impacting that app and simply an annoyance to you which can safely be ignored.
I find the @mbluke recommendation quite troubling. I’m sure that completely disabling suggestd is going to solve your issue, but at what cost? All of the apps that benefit from the use of suggestd will completely loose it’s functionality. If you really can’t live with the issue, then you should only change the MachServices to “No” one at a time until you find the culprit and leave the others as “Yes”. Recognize that will take more time, but IMO vastly better than totally disabling it.
