I am running into this problem as well, but only sporadically, and only
in my 3.1 test environment, not 1.4.1 production. I may have narrowed
things down, I am interested now in learning whether this is a problem
with the MySQL connector or DIH.

correctly (using DIH, with one big SELECT statement for millions of
rows) instead of solving this specific problem. Here's a partial
stacktrace from this specific problem:
