[pro2pop]

Hi. I have a problem with periodic stuck in sync of node&wallet. Last time its taked me off and ive del wal and node db, and reinstalled the program. Two days process of sync was active, but now it stuck one more times. Reboots, prog restarts, disconections from nodes are not help...
In log:
