Failed to add bandwidth usage

Node Operators troubleshooting

I’m using Toshiba 6TB HDD, encounter the same error.
After add setting:

# Maximum number of simultaneous transfers
storage2.max-concurrent-requests: 20

Then it works!
No more “Failed to add bandwidth usage” errors, no more node suspended.
