Failure initializing the client layer

Failure initializing the client layer
July 24, 2019 04:53PM
Hi everybody.

I'm getting a weird error on some windows services developed in WD20 and access to MySql database with Native Access.

Randomly they run into a native access error (not exception) with an error description of
"Failure initializing the client layer"
From that, no way to run a query with success until a manual restart of the service. Then everything goes fine until the next Failure.

Depending on the customer, with then same WD environment, MySql and services installed, I find this error on log files sometimes 1 time a day or 2 time a week. I can't figure the relation with something else, software upgrades or other stuff.

Some months ago this kind of error never occurred and now I can't get rid of that.

Do you know something about it?

Hi stefano,

Sorry for the late answer, I leaved on vacation.
No BEX in then event viewer log.

This is the full log there. tab_pv is a very simple table containing the list of branches of a company.
My MySql connection switches beetween several databases in order to compute data. Each DB is the DB of branch's data.
