Great, thanks for doing this! Lets see what the reaction is.

An update on this: the above bugzilla issue has a pointer to another entry which describes a memory leak in openssl-pkcs11 package:

https://bugzilla.redhat.com/show_bug.cgi?id=2097690

Bug 2072962 comments discuss how the leak appears to be caused by openssl-pkcs11. I have also received additional confirmation that if openssl-pkcs11 package is removed, the memory leak does not occur.

PKCS11 package is needed when, for example, secret key resides on a hardware security module (HSM). openssl-pkcs11 package is not installed by default on RHEL 7, Ubuntu 20.04 and 22.04 and it's not required by Radiator. Therefore, if you are running Radiator on RHEL 8 and see a memory leak and do not use a HSM, you can check if removing openssl-pkcs11 helps.

Testing with Ubuntu 20.04, for example, shows that the leak does not appear when Ubuntu's respective PKCS11 package is installed. It seems that the leak is specific to the version in RHEL 8.

Thanks,
Heikki
