What does HRESULT 0x80290218 (TBSIMP_E_TOO_MANY_RESOURCES) mean?

TBSIMP_E_TOO_MANY_RESOURCES

The TBS resource table is exhausted

TBSIMP_E_TOO_MANY_RESOURCES (0x80290218) means the implementation is already tracking as many virtualized TPM resources as it can for the relevant scope. It is not ordinary process heap exhaustion.

Evidence to capture

Record TBS context, number/type of loaded keys/sessions/resources, virtual-handle table state, and which operations should have released resources.

Focused correction

Flush/release resources no longer needed and correct leaks in object lifetime. If the limit is specifically TBS contexts rather than resources, preserve TBSIMP_E_TOO_MANY_TBS_CONTEXTS.
