It seems dovecot is impatient with connecting with mysql, as I see in maillog entries like:

I suspect it does connect eventually. This is a test system with only 1GB of memory and free reports:
total used free shared buff/cache availableMem: 1025484 696344 24556 21528 304584 251552 Swap: 524284 92168 432116
The production box has 2GB, so if the problem is mysql is swapping out, that will be 'fixed', if it is processor, well this is an ARMv7 duo core, as is the production box. I am considering buying the new quad core.
Is there anything I can do to get dovecot more patient with mysql, or just ignore there messages?
thank you I really don't understand how you reached to the conclusion that dovecot is impatient.
Well, it waits a varying amount of time before reporting the connection failed. Not a fixed amount of time.
Why mysql takes so long to connect via a sock is separate, but I suspect it is the low memory and duo core limitations.
Maybe the question is more what is mysql not doing to take so long to respond to the connection.
