I'm having a problem when I do a course backup, and include all the related logs... everything seems to smooth (temp files are created properly) but when it tries to create the zip file, it just hangs and never fully finishes (leaving a corrupt zip file). It works fine on small files, it's just with large files that the problem occurs.
I'm working with my host, and we have raised memory limits, but there is still problems. My host wanted to know if "Moodle itself is limiting memory? Are they using use ini_set to override the memory_limit setting?"
So is there an ini_set memory limit for Moodle that could cause the backup to hang for large files?
