With regards to the wallet I think they mean that it stops syncing if you have it open and you must close and reopen to get it to sync. I have the same issue. I noticed that p2pool was finding blocks but they were not showing in my wallet. I closed and reopened the wallet and it showed it was several hours behind. Then it was bam bam bam! as all the coins started hitting my wallet. I have had to do this numerous times.
i firgured out that cause by nodes (some nodes have corrupted data or not responding). just delete the old peer data ( peers.dat file ) and remove all nodes in logicoin.conf then start wallet again, first time searching for peer take a bit longer but will be stable soon.
