now as you can see the time differance between the found blocks ,but its all at the same-height and been summited seperatly.......Now this resulted in 3 orphans out of the 4

question is the daemon issuing poor work units ?

thanks for the pic it shows an issue i have been trying to recreate for some time now because me and a few others have had this happen but like a dumb ass i didnt get a screen of it.
i have no explanation for why but i have mentioned that at times it appears the DB gets behind and stacks the blocks and re-reports found blocks to miners which confuses the crap out of people. at times it does same to blocks found in user accounts. Maybe steve or chris can explain this

i have pages and pages of this happing,costing alot of my miners hashing time

heres 3 morescreenshots i just flicked back a few pages to see it going on and on
