Hello, this sounds like a known limitation of the openssl provider: https://github.com/tpm2-software/tpm2-openssl/issues/4 Some applications (like CMP) are too greedy and consume more resources than the TPM has. The resource managers (to my best knowledge) cannot swap resources from the same user. Are you using the tpm2-abrmd resource manager, or the in-kernel manager? The tpm2-abrmd behaves much better.
