Issue not fixed by me turning off Windows Firewall and Defender (I don't have any other antivirus or firewall).

I have noticed the same thing since v16.
The downloaded blocks count goes from 30000 to 29500 in ~1 hour...
The wallet does not crash though.
I am using ubuntu 64.

switched back to v15.2
it went from 27000 to 3000 in 5 minutes...

restarting v16 helps in decreasing the downloaded block counts (a few thousands during the first 10 or 20 minutes, then it slows down a lot)

Same thing happening here in Ubuntu 18.04 64bits.

This should now be resolved in V16.1, which has just been released. If it has not, please re-open this ticket so we can track it further. Thanks !

Here's my experience with v16.1 on a powerful Win10 x64 rig with gigabit connection.

Deleted exisiting db for a fresh bootstrap. After running for 7 hours had reached about 13.28 / 13.45 million blocks. It had likely reached this point a few hours earlier. Seemed to have stopped syncing further or at best going extremely slowly. Logs look normal.

Restarted the node and within a few minutes perfectly in sync.

So doesn't seem entirely stable / fixed yet. But better for sure.
