What is with these strange errors on installation?

Permalink
An exception occurred while executing 'INSERT INTO ConfigStore (cfKey, cfValue, uID) VALUES (?, ?, ?)' with params ["NEWSFLOW_LAST_VIEWED", "FIRSTRUN", null]: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'uID' cannot be null.

I'm trying to install an empty site on a vps.

I've got the report from a concrete5 Japan user with the same error message on 5.7.5.3 install as well.

We need more detail info about servers.

I've fixed it on my setup by turning off my load-balancer.

Seems the error occurs when 2 server are trying to share the work when installing...
