RemoteGoTask::__call failed, because unable to read prefix from socket: File exists

[celosauro]

We have upgraded the swoole version from 5.0.3 to 5.1.6 and it has randomly started the following warning:

RemoteGoTask::__call failed, because unable to read prefix from socket: File exists (17)

Anyone has any hint about what's can be happening?

We're using a Hyperf application that uses GoTask to create a socket connection to mongodb

This may require the Fastmongo project developer to debug it.
Not sure how to run the project and the steps to reproduce the problem. We need to clarify which Swole APIs were called and which differences caused the aforementioned issues after the version change.
