MOODLE_25_STABLE
Description
I installed APC on MACOSX. I noticed some fatal errors that do NOT crash anything - all my Moodle sites seem to work correctly whenever these errors appears in my php error logs:

I suppose it's only APC that stops as my sites are still as slow as usual. I did not look much more than quickly googling "EDEADLK". I deduced that it's a problem with my config. I'm writing this tracker issue in case it's not a config issue but something important that you may want to know...
