C51 question

Hey guys, why would I get the following errors if i comment out a piece of code? the code is in my main loop.

*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: DATA SEGMENT: ?DT?PROCESS_TEL?PROCESS LENGTH: 0009H
*** ERROR L107: ADDRESS SPACE OVERFLOW SPACE: DATA SEGMENT: ?DT?_ASC_TO_BCD?MISC LENGTH: 0008H

Thanx :)
