I would definitely upgrade to 4.1.9. This version contains a set of
stability fixes concerning event handling which helped me to solve

From the ChangeLog "... Event and timer handling re-design, again. This
fixes a bug, which possibly existed since version 3.9.8 and freezes
threads under heavy load..."
