Error Compiling class

Hi, 

When I try to compile a specific class it fails and gives the below error message.
ERROR #5002: Cache error: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
  > ERROR #5030: An error occurred while compiling class 'ClassNameHere'
Is there anything I can do to fix this issue?
Thank you in advance for your response.
