Thanks for your reply
How can I understand when it's enough to increase things? Is there any
manual way to get current values of each buffer, etc?
Also since I'm logging a lot of things I'd love to know if there are some
other ways to lose messages without seeing them in "dropped"?

So you propose just randomly tune those params? I just don't understand how
should I get check if it helped. I need to see the current state of each
buffer(to be able to get some statistics data) to see if it helps.
And one more specific question:

messages, the other destinations do not receive any messages either,
because syslog-ng stops reading the source.
Why there is no messages about it in syslog-ng logs? It must be error,
don't you think so?
And what if I don't have flow-control enabled?
