WORLD_CLIENT_ERR and constantly rebooting zones

[Randymarsh9]

I have been having two problems since bringing my server up, and I still have not found a solution to either of them. Occasionally, when someone zones or logs in, I get a huge list of messages in world.exe saying WORLD_CLIENT_ERR followed by a long string of random characters. Also, my zones crash a lot which is possibly related to the former problem, but sometimes, they will restart and shut themselves off over and over again. For instance, one dynamic zone rebooted itself 3000 times even though nobody was in it. I was just wondering if anyone has solutions to these generic problems or any tips for dealing with them.
