I've added more than 20 maps into my server and still there are more to be added in. But now as the amount of custom maps keeps increasing I found it unable to join the server. Everytime I join it shows a message " Crashed with address 7033F77E. Log created to crashlogs folder. ". So does it have some restrictions on custom maps or something?
Yes. There is a limit on both, the XML objects and custom objects. Although none of the limits are documented anywhere.
