Various issues with traffic through a cluster:

• Random traffic outages
• Dynamic / Static routing stops working
• Users are not recognized by Identity Awareness
• All Identity Awareness commands on cluster members show: "daemon did not respond or not running!"

/var/log/messages file on cluster members repeatedly shows:
FW-1: cxl_status_update_register: registering Name_of_Process not successfull because too many processes are registered.

Examples:

• FW-1: cxl_status_update_register: registering pdpd not successful because too many processes are registered.
• FW-1: cxl_status_update_register: registering pepd not successful because too many processes are registered.
• FW-1: cxl_status_update_register: registering routed not successful because too many processes are registered.
• FW-1: cxl_status_update_register: registering cprd PID 22279 not successful because too many processes are
• FW-1: cxl_status_update_register: registering cvpnd not successful because too many processes are registered.
• FW-1: cxl_status_update_register: registering ted not successful because too many processes are registered.
• FW-1: cxl_status_update_register: registering gated not successful because too many processes are registered.
registered.

After enabling generation of core dump files per sk92764 / sk53363, core dump files for various processes might be generated in the /var/log/dump/usermode/ directory:

• fwd
• routed
• pdpd
• pepd
• cvpnd
• gated

Output of "cphaconf debug_data" command (under cluster debug 'fw ctl debug -m cluster + conf') on cluster members shows that cluster subscriber list is filled only with instances of FWD daemon (refer to sk93306 - Chapter 'ClusterXL Monitoring and Troubleshooting' - section "'cphaconf' command" - "cphaconf debug_data").
