Occasionally I run into task launch failures with error message: Invalid job credential. slurmd log shows that job credential verification failed with openssl error string "block type is not 01". A restart of the slurmctld will remove this problem but some time later it will happen again.
We are using RSA for job credential keys. I googled and it seems this issue may be caused by openssl sign/verify padding scheme. But I do not know how to fix it. Does anyone else has this problem?
