Error Messages Crashing Server

I seem to get these errors in console.log right as the server crashes.


Entity 66 (class 'prop_physics') reported ENTITY_CHANGE_NONE but 'm_iHealth' changed.
Entity 66 (class 'prop_physics') reported ENTITY_CHANGE_NONE but 'm_hEffectEntity' changed.
Entity 66 (class 'prop_physics') reported ENTITY_CHANGE_NONE but 'm_iHealth' changed.

This has happened several times.
