High concurrent visiting neo4j database ,appears IO ERROR " io driver has terminated". How to solve it?

[pengyizeng]

Recently, I try "neo4rs"," Deadpool-bolt", "b88-bolt" to create connection pool with neo4j. My program appears

"error:UnexpectedMessage("unexpected response for RUN: Err(IOError { detail: "IO driver has terminated" })")"driver has terminated"

when many query appears in a short time. How to solve it ?

I have google the error , but I did not found any useful information.

This error means that the Tokio runtime has been shut down, but something is still trying to use an IO resource from the runtime.

It sounds like maybe this is part of a termination process that isn't graceful? If so, you can look at mini-redis to see how shutdown is done there. E.g. here and see the rest of the file.
