The following 2 php error messages below occurred many times during a moodle outage a few days ago (Moodle was unresponsive, IIS restart required to fix it), I've included the IIS log entry for the same moment too.
It looks like some data integrity problems for a course resource? Can anyone shed any light or suggest something I can do to further investigate the problem?
thx,
