wrt Cryptsy Xactions, @K1773R knows how to fix them ....
One I had stuck had 400 inputs, I think K1773R rebroadcast it ... not sure, maybe that's something a cron script anywhere can do ... just my bit's worth
No, the person with the stuck tx (sent or recieved) has to rebroadcast it, so i recieve it. all i did was changing max tx size and block creation settings. i pointed this out at some other posts already.
