well heres one thing that does it...

say u send a mesage and it fails, it auto saves in drafts as well, click the link to resend, the delete the errored message from the threaded txt..this should delete it from ur drafts as well, on stock 6.1 at least..

the reason for this is, everytime to soft reset, your drafted(errored only) messages auto send once you get signal on the restart..

i know not a major fix fo you, but it will cut it down..

oh yeah, also if you lose/regain signal alot(go in and out of roam) all those uncleared "resend now" message will resend everytime untill you deleted said erroed message
