Describe the bug
CFE_TBL_Register fails to register new SC tables when a bigger number of tables are used.
This was not a problem before draco-rc4 I guess, because it was introduced in the MemPoolGeneric module.
To Reproduce
Steps to reproduce the behavior:
- Set RTS Tables to 512
- Change de RTS tables maximum words to 3000
Expected behavior
CFE_TBL shall have a fail stat (log below) and SC is killed.

System observed on:
- Hardware
- OS: Linux Ubuntu 24
- Versions Draco-rc4
Additional context
I may open an issue in CFE_ES, once its not quite just a SC bug. Also, using cFS 6.5 it was pretty ok to use 512 RTS tables with 3000 words, the difference was that no MemPoolGeneric existed to manage the tables register.

Research direction
Start by reproducing the failure with 512 RTS tables and a 3000-word maximum, then trace CFE_TBL_Register through the MemPoolGeneric module. Compare this behavior with cFS 6.5 if available; done means the larger SC table configuration registers successfully without the reported pool-allocation failure.
