Using 2.4.44 on centos 6 with multimaster 4 ways. I have been noticing more unsynced entries from the master on the consumer side ever since I have enabled chain overlay to pass ppolicy failure from slaves to the master. 

While the problem is not frequent, it has cropped up quite a few times so I tried using -c to force reload but this doesn't seem to work even though, contextcsn on the producer and consumers are equal. Only real solution so far has been wiping out data.mdb then restarting the slapd which 100% fixes the problem. 

Am I misreading the man page where providing rid only with -c  forces full reload? 
Also, anyone seeing unsynced entries even though contextcsn is in synced?
