Thanks a lot for your feedback. Please remove this line "pthread_mutex_t lock;": in the trustm_engine_common.h https://github.com/Infineon/linux-optiga-trust-m/blob/44f942c04424c03970242281667f01a5aa442d49/trustm_engine/trustm_engine_common.h#L171
For greater stability and performance, please upgrade to development_v3 branch https://github.com/Infineon/linux-optiga-trust-m/commit/1718b8211f01738373f5e45548c964d2138a0a6a
