No DHCP Relay, just local DHCP Server on the mikrotik on the bridge that
all the AP's are part of.
No MAC limit on the SM's
When it exhibits itself, a customer who has been running for weeks will
timeout their lease, and the mikrotik will just go to 'offered'
Rebooting the AP always fixes it.

I was wondering about broadcast rate limit. That would apply to a
DHCP discover, but not to a renewal. ….but either the MAC limit or
broadcast limit would clear when rebooting the SM, and he says
rebooting the SM has no effect.
Is DHCP running on the port that the AP is plugged into, or is there a
DHCP relay involved?

Do you have the SM limited on MACs? Look at Ethernet Port Security on
config > network.

I've experienced this issue randomly, and haven't been able to track
down a cause. Wondering if anyone else has come across something
similar.
Mikrotik DHCP Server. EPMP1000 GPS AP, Force 300 SM.
At a random time, one or More Force 300 SM's on the AP will lose the
ability to hand out a DHCP Address to the client. The Mikrotik just
shows 'Offered'
Rebooting or powercycling the SM has no effect. If the SM
Connects to a
different sector, then DHCP is immediately handed out. If the AP
reboots, and the SM reconnects, then DHCP is immediately handed
out. If
the SM is set for NAT mode, it can get a DHCP Address just fine, but
switching back to bridge, the Customer router will not get DHCP.
I've experienced this from 4.4.3 all the way up to 4.6.3. It always
seems to be an EPMP1000 AP with a Foce300 SM, but does not affect
every
Force300 SM at the same time.
At least now I know when I start having this problem to go reboot
the AP.
