FreePBX/Asterisk Errors, any ideas?

Had a call from a client stating they were having issues with calls in a queue not being sent to agents, and sure enough I saw available agents and yet there were people in queue for 15min just waiting (patient people I tell ya). The system is a current FreePBX Distro 5.211.65-9

That said I went to look at the config, and the logfiles to see if anything stood out, and I see a bunch of errors like below:

d to Local/s@tc-maint

This I keep seeing repeated over and over in the log, so it doesn’t like something that is going on.

Any ideas, has anyone run into this one before?

the tc-maint reference is to time conditions cron job, check that you haven’t screwed that up first, but it is probably a spurious error for your problem.
