It probably won't, but it will prevent a re-occurance before you get around to
the 8.1 upgrade. How much time have you wasted on this issue already, an
issue which might not have occurred if you'd kept up with patch releases? A
patch upgrade is what, 5 minutes of downtime?

Well, that would be in line with the issues 7.4.7-7.4.12. All of them require
millesecond-timing to hit the bug. You're not likely to see it more than
once.
