To cleanup running and pending requests we use cmclean.sql, If we stop concurrent managers using abort options then concurrent requests will be in running state ,Next when we start concurrent manager the processes will not start properly.

CMCLEAN will update below tables:
1) FND_CONCURRENT_QUEUES
2) FND_CONCURRENT_PROCESSES
3) FND_CONCURRENT_REQUESTS
4) FND_CONFLICTS_DOMAIN
5) FND_CONCURRENT_CONFLICT_SETS
