After maintenance cleared an open forward cargo heat log entry as 'unable to duplicate;' the warning recurred during taxi-out. The system was deferred again; some 'small arms ammunition' relocated to another cargo area; and the flight continued.

Narrative:
Aircraft had a deferred forward cargo heat detector. Maintenance cleared the item; saying they could not duplicate. On taxi out we got a forward cargo overheat and returned to gate. The forward cargo compartment had hazardous material stored in it labeled 'explosive - small arms ammunition.' I believe someone should have avoided loading explosive cargo in a compartment with a history of overheat type faults. We ordered the cargo moved from this compartment; maintenance deferred cargo heat with no action; and we departed. It is interesting to note that both dispatch and maintenance control wanted to have the problem fixed; but local maintenance said there was no time to do so and deferred it again.
