Hello!

I have a lot of errors: (-1). In your documentation: «and Error Codes \< 0 are client generated errors» In C errors there are explanation: «Generic client API usage error» We are using php client one of last versions.

So what the problem? What we can do for working? php7.2-fpm

You should reconnect to aerospike. It will work after.
