Just saw this on the terminal:
Removed /home/[user]/p2pool/data/bitcoin/shares.43I've never seen this message before.
Does anyone know what it means / indicates?
Is it something to worry about? - I love playing the conspiracy theory card
No, it happens all the time. Old and unnecessary share data files are removed regularly so p2pool doesn't completely fill up your disk with them. You'll especially notice it if you happen to have shut down your node for a few days, and start it back up.
