Load data to mongodb error

[ljgreen]

When I try to load data into mongodb, it throws the error like this.
2019/10/07 17:58:37 Bulk aggregate update err: read tcp 127.0.0.1:58292->127.0.0.1:27017: i/o timeout

I use the command:
tsbs_generate_data -use-case="devops" -seed=123 -scale=1000 -timestamp-start="2016-01-01T00:00:00Z" -timestamp-end="2016-01-02T00:00:00Z" -log-interval="10s" -format="mongo"| gzip > /tmp/mongo-data.gz
Anyone also encounter the same issue?
