Preload hung at mid process in v3.2.10

I updated to v 3.2.10 and ran preload. The process stopped midway through. I left it as is, but eventually it crashed the website. I checked the debug log and found WPO(preload) had generated too many queries and exceeded the maximum allowed for my hosting plan.

Also when the preload first initiated, the “Unexpected response . . ” message popped up. I thought this should have been corrected with this new version.

In any case, these two issues have been there since v3.2.4. Now I have to roll back to 3.2.3.
