    When doing a bulk regenerate of images, and having it set to “Skip regenerating existing correctly sized thumbnails (faster).”

    It runs for around 200 images, and then stops with the following in the error log. Any advice?

  • Update – if I regenerate from the media library and bulk select 300 at a time, it seems to be both a lot faster in processing, and doesn’t error. Not sure why.

    Hmm, it seems your MySQL server doesn’t seem happy.

    Does it work better if you uncheck “Update the content of posts to use the new sizes.” ?

    This was with that option unchecked. I worked around it by just doing them 300 at a time in the media library, which took a bit more time, but was way faster in terms of per thumbnail generation.

    Weird. Well glad you got it sorted. 🙂
