Hi, guys i have a problem...can't sync my qt wallet, it ctuck on 2097394 block...i downloaded v1.4.17 from official site, downloaded bootstrap.dat from this
https://bitcointalk.org/index.php?topic=623147.msg9772191#msg9772191 post and put it in folder where my wallet.dat is....it goes fine till wallet renamed it (bootstrap.dat.old) sync stopped on that block...I made clam.conf and add some nodes but still nothing...on client i see a have 16 active connections... "importing blocks" in lower left corner is gone and it's really annoying because i lost 5-6 hours (in last 4 days) on this...

Finally, after 10 days i was able to sync my QT wallet...in 5 years of my mining experience i have never seen .....naaaah, it takes to much of my time... never mind. Good luck to all who have this....."coin".

Very slow syncing is a known problem with the CLAM client... unfortunately no one has figured out why, yet. If your client stays open everything works fine, but if you leave things for a few days, the debug log gets filled with errors like "ORPHAN BLOCK 751" and "already have block..."
Just a warning, do NOT use Yobit for CLAM (or anything, really)
I found the workaround to set the maxconnections=1 - then you will be receiving blocks only from one source and there will be no competition/false orphans (my guess is the client is receiving the syncing blocks from the past AND the current blocks together)
