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.

This error is associated with a problem in the namespace’s Extent Manager information rather than with the class source itself, especially if the same class compiles in other namespaces or environments. One reported explanation is corruption or stale extent information for that namespace. [1][2]
Things you can try:
-
Run:
##class(%ExtentMgr.Util).DeleteExtentDefinition("ClassNameHere")
This was suggested as a way to remove the registered extent definition for the affected class, though it may not fully resolve the issue in all cases. [1][2] -
If that only helps temporarily, one reported fix was to delete the whole
^rINDEXEXTglobal and then do a Rebuild All. In the reported case,DeleteExtentDefinitionfixed only the first compilation, while deleting^rINDEXEXTand rebuilding resolved it. [1][2] -
Another practical workaround is to export your classes and import them into a fresh namespace, since the issue was observed to be namespace-specific. [1][2]
The issue is not considered normal behavior. One InterSystems comment stated that all registered extents can be rebuilt from compiled class information and recommended opening a case with InterSystems Support / WRC so they can analyze why it is happening. [1][2]
Warning: It also causes the compiled class's extent (the data!!) to be deleted so be careful. [1][2]
If you delete classes in the future, the /deleteextent qualifier was mentioned as a way to also remove the Extent Manager registration and keep it cleaner, but it must be used carefully because of the data deletion impact noted above. [1][2]
Also, the <FUNCTION> part of the error means “The specified function does not exist or is being used improperly.” [3]
