调研方向
Start by tracing the reconnection retry path indicated by the gasket::retries warnings and identify the worker that retries connections to cardano-node. The report shows repeated connection-refused errors and 100% CPU during an outage; determine what causes the excessive CPU and make retries avoid it. Done means reconnection continues while CPU use stays reasonable during an outage.

描述
So I noticed when there is an outage of cardano-node, scrolls tries to reconnect (this is great) but the small issue is that this reconnection watchdog/ daemon or worker in scrolls process is consuming way more CPU of the machine than it should.
