TBSIMP_E_OUT_OF_MEMORY

The TBS software layer hit a memory-allocation failure

TBSIMP_E_OUT_OF_MEMORY (0x8029020C) is a host-side implementation resource failure, not TPM NV capacity and not the TPM_E_IOERROR transport code.

Evidence to capture

Capture process/service memory usage, allocation size if known, context/resource counts, leak indicators, and system commit pressure at the failing operation.

Focused correction

Reduce leaks/resource fan-out and restore normal memory availability, then retry with a fresh context if needed. Do not clear TPM keys as a response to software heap pressure.
