TBSIMP_E_TOO_MANY_TBS_CONTEXTS

The implementation reached its TBS-context limit

TBSIMP_E_TOO_MANY_TBS_CONTEXTS (0x80290217) means the application/system has exhausted the number of simultaneous TBS client contexts allowed by the implementation. TPM key count is a different resource dimension.

Evidence to capture

Record process/user context count, context creation/destruction paths, failed cleanup, and whether contexts survive thread or request completion.

Focused correction

Close unused TBS contexts and ensure every successful create has a matching close. Reuse a context where the API/lifecycle permits rather than opening one per command.
