An error message is displayed when TCP-Analytics fails to save new data. This error message is not rate-limited, as all other TMM error messages are, so if the error situation is encountered very frequently, the message will be displayed only occasionally, and not for every error event. Since the error message is not rate-limited, hitting this error many times might eventually lead to TMM halt.
TMM can halt. Traffic disrupted while tmm restarts.
-- TCP-Analytics is assigned to virtual server. -- The aggregation method of TCP Analytics causes a full table situation because of the distribution of the client IP addresses and subnets.
Remove TCP-Analytics from virtual servers.
Error message is performed with rate-limiting mechanism.
