Bitcoin core verification keeps reseting I'm trying to run Bitcoin Core service with full node verification on Ubuntu on testnet and it keeps resetting. The verification increases to 0.3, then resets to 0, for 2 days already. Debug.log records look like there was a process crash, but no reason mentioned: 

The server is Digital Ocean's droplet, I've already tried to increase the server CPU/RAM, no luck. Want to find the reason of what is going on here, what exactly causes such behavior.
As 0x49D1 reported: reducing the Bitcoin Core database cache helped to reduce memory usage, which caused the crashes while syncing.

In bitcoin.config dbcache=&lt;n&gt; or as command-line argument -dbcache=&lt;n&gt; where n is the database cache size in megabytes (default: 300)
