The ips_pcb_cache stat keeps increasing while the system is passing traffic.
Increased memory usage of ips_pcb_cache and may lead to tmm crash. Traffic disrupted while tmm restarts.
- IPS licensed and provisioned. - Port missing from service or - Port configured for service that does not match traffic.
Add TCP port (e.g., port 443) to the respective service on the IPS profile. For example, with a virtual-server that is configured with port 443, the port should be added to HTTP service if it terminates SSL (e.g., has client-ssl profile), otherwise the SSL service.
