* Client makes a 'getinfo' call and don't receive a response in a minute.
"What is your precise RPC usage? "
One process is asking getinfo every second as a fallback to possibly misconfigured blocknotify. It also calls getblocktemplate every 30 second.
Second process is calling getinfo once a minute to check if bitcoind is working. If it don't receive a response in a minute, it kills bitcoind and starts it again.
