I am trying to reproduce the issue but currently without any success. I
have a presupposition that it can be a synchronization issue between GC
and main driver logic but I haven't any evidence of it yet. Probably, I
can't reproduce some environment's peculiarities.

So, I think that I need to understand more deeply a workload in that the
issue had occurred. As I remember, you talked about several MySQL
databases and so on. Could you describe in more details about what
applications and how to work before issue occurrence?

Thanks,
Vyacheslav Dubeyko.
