Unable to allocate memory for pool

[eluser]Unknown[/eluser]
I realize the following error: "unable to allocate memory for pool" in mx loader appears because of high server activity and I should increase my memory in php.ini. However is there a way to hide such messages?

It wouldn't be friendly to show such ugly red errors to website visitors it may freak them out. Is there a way to mask such errors in a friendlier fashion?
