On Gateways with PKI enabled, the revoked certificates are stored in a Certificate Revocation List (CRL). If this list grows too long, generally due to an issue with the Certificate Authority of the Orchestrator, the performance of the Gateway is impacted. The CRL should be less than 4000 entries long.
Use the following command to check the CRL entries.
vcadmin@vcg1-example:~$ openssl crl -in /etc/vc-public/vco-ca-crl.pem -text | grep 'Serial Number' | wc -l 14 vcadmin@vcg1-example:~$
