See this link: https://www.cisco.com/c/en/us/td/docs/ios/system/messages/guide/sm_cn02.html#wp607533

 

 

%CERM-4-TUNNEL_LIMIT : Maximum tunnel limit of [dec] reached for Crypto functionality with securityk9 technology package.

 

Explanation    The message indicates that the maximum limit on the number of tunnels for the crypto functionality has been reached. The indicated number of tunnels is the maximum that is allowed with your securityk9 license.

 

Recommended Action    Upgrade to the HSEC-k9 technology package to remove this limitation.

 

About the number of tunnels, please see this other link:
