Error: send que size more than ABSTRACT_SERVER_SEND_QUE_MAX_COUNT

It means communication with that particular peer is stuck. It can be ignored, and is likely fixed in master (hard to be 100% sure).

How/when does the --db-salvage flag get used? What's it do?

bad balanced CURRENCY_BLOCK_GRANTED_FULL_REWARD_ZONE constant

The issue sounds like a wallet has a wrong view of what outputs are spent. A fix would be to rescan the wallet (rescan_spent or rescan_bc in Monero's wallet, or delete the cache file). The "full ...

Transaction rejected by daemon with status: Failed Error: Reason: fee too low

There are two main reasons a program can not bind to a socket: the port is already used: typically, for the Monero daemon, this means another monerod is already running. You can check whether monerod ...

"Failed to lock C:\ProgramData\bitmonero.daemon_lock"

Most likely you were running it before and killed it uncleanly. Windows takes a few minutes to notice that the owner of a file lock has died, before it cleans up the lock.
