Can you give me a little pointer on how and where to do the verbose 
logging? I am really interested in discovery why I am getting the large 
osdmap message. Maybe it is because of the snapshot being created?

I'm not sure.  I wouldn't expect one unhealthy PG to trigger a large 
osdmap message.  Only verbose logs can tell.

Thanks,
