[CentOS] Proper check of openssl usage in processes?

Hi All :)

I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the old openssl version is still used - if it is still used (I think that without a process restart the old version will be used) I will perform restart of the process

Can this kind of check be done in some other way?

BR, Rafal.
