Description

Follow-up of #2957

At least 2 customers reported random issues with database connections that seems to be fixed when remote config is disabled.
For one of the reports, the error was EINPROGRESS (Operation now in progress), which could seems unrelated, but actually a bug in PHP (likely fixed by php/php-src#16606) could return this error while the real one is EINTR

Reviewer checklist

• Test coverage seems ok.
• Appropriate labels assigned.
