Detail

Following Critical Assertion is seen in the logs on Centos 9 or Debian 13:

But also these lines are important

Answer

Issue observed when upgrading to versions of the Openssl Library 3.4 (and above):

openssl-3.5.0-1.el9.x86_64.rpm          
openssl-libs-3.5.0-1.el9.x86_64.rpm 

Current workaround is to downgrade the two packages to a version below openssl 3.4, or to upgrade Aerospike to a version that has the issue resolved.

yum downgrade openssl-libs-3.2.2-7.el9.x86_64 openssl-3.2.2-7.el9.x86_64
