Hello 672042564@qq.com,

Thank you for the report. Looking at the output provided it appears that you've hit the open file limit on your system:

2017-12-19T16:28:34.803+0800 E - [conn5] cannot open /dev/urandom Too many open files

This can be increased to a larger number of files to avoid hitting this error.

Please note that SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-user group.

Thanks,
Mark
