TBSIMP_E_HASH_TABLE_FULL

The virtual-handle lookup table is exhausted

TBSIMP_E_HASH_TABLE_FULL (0x80290216) means an internal TBS implementation table used to map virtualized TPM handles has no free entry. This is an implementation resource limit, not a TPM authorization failure.

Evidence to capture

Record virtual-handle count, resource/context lifetime, create/flush operations, and whether mappings survive failed commands or client teardown.

Focused correction

Release stale virtual resources and fix handle-lifetime leaks so table entries are reclaimed. Do not reset the physical TPM simply to clear a software mapping leak unless required by supported recovery.
