We wrote an application (on Zope v2.7.6-final) that queries a MySQL

DeadlockDebugger can confirm what your problem actually is.

Is this a bug in version 2.7.6 or ZMySQLDA ?

Likely neither.

Or are there some settings I can tweak to adjust some database

You might wanna ask on a MySQL list. Also follow others' advice to find out why you MySQL server isn't responding.
