Hi Team,

I used the following commands to back up the database. At first, there was no problem, but after running for a period of time, the following error was reported. In my environment, the error is inevitable. I don't know what the problem is. Please give me some advice.

command:

mongodump -h 127.0.0.1 --port 27017 --authenticationDatabase admin -u ****** -p ****** --authenticationMechanism=SCRAM-SHA-256 -d db -c collection  -q '{"source": ["114"]}' -o /data/url

running log:
