Server crashes when I type skills or spells in mud?

Everything compiles correctly no errors but now while walking around in the mud when you type skills or spells to see either one it crashes. Any idea where to look for the problem?
I started using 1stmud 4.5.3 which is a rom 2.4 mud base.

All that has been changed is my imp character has obtained all the skills and spells and since then the server crashes when i type spells or skills.

The only other change I made was to the MAX_LEVEl changing it to 400 but it was working fine after that change.

Any help would be great in finding the problem my log file says nothing.

Thanks
