TPM_20_E_OBJECT_MEMORY

Resident object memory is a limited TPM resource

TPM_20_E_OBJECT_MEMORY represents TPM_RC_OBJECT_MEMORY. A TPM can store persistent object metadata and also load a smaller number of transient objects into protected working memory. This warning means the command needs another loaded object slot but all available object-context memory is occupied.

This is not Windows virtual-memory exhaustion and should not be handled by enlarging the process heap. With a resource manager, objects can be context-swapped automatically; direct TPM clients must explicitly flush or save handles they no longer need.

What to inspect

Enumerate transient handles and identify objects whose lifetime has outlasted the operation that created them.
Close TBS contexts so their associated objects can be flushed.
Use a resource manager for concurrent clients rather than sharing unmanaged raw handles.
Do not evict a persistent key merely to free transient memory; persistent handles and loaded-object slots are different resources.
