I'm currently running rpc node with the following config:
exec solana-validator \
--identity /home/ubuntu/validator-keypair.json \
--known-validator 7Np41oeYqPefeNQEHSv1UDhYrehxin3NStELsSKCT4K2 \
--known-validator GdnSyH3YtwcxFvQrVVJMm1JhTS4QVX7MFsX56uJLUfiZ \

--full-rpc-api \

--wal-recovery-mode skip_any_corrupted_record \
--limit-ledger-size
However, every 4 hours it start to download snapshot from other node, which I assume is because is loses some slots during synchronisation.

Why is the happening and how it can be resolved? Because during download, node is not operational
