My server crashes on map change

GreyFlcn

<div class="IPBDescription">When it crashes</div>Is there anything I can improve on the mapchange to make sure it doesn't crash?

Note this isn't the part where it drags everyone into the readyroom.
It's the part right where the next map starts loading.

This is really putting a damper on my server since it loses all playerbase momentum after a crash <img src="style_emoticons/<#EMO_DIR#>/sad-fix.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad-fix.gif" />

Note: I have these things installed
