NOTICE Messages

Im using freepbx 2.9.0.12 From the distro, I have a 4 port ISDN2 card and all seems to be working fine but at the asterisk cli I get the following repeatedly even when there is no call activity.

== Spawn extension (tc-maint, s, 4) exited non-zero on ‘Local/[email protected];2’

I’d apreciate any advice that anyone can offer.
