Opened: Sep 27, 2023

Severity: 3-Major

Symptoms

TMM forwards client request to ping_access_agent for processing. Each request forwarded to ping_access_agent creates a request-specific context within ping_access_agent. When the request processing is completed, this context must be freed, this does occur when the request processing reaches a normal conclusion. If the client connection in TMM fails before the request is fully processed, it is TMM's responsibility to notify ping_access_agent to free the context associated with the connection. If TMM fails to notify, the context is "orphaned" and will never be freed, thus causing ping_access_agent to grow over time as more contexts are orphaned.

Impact

Pingaccess agent leaks memory over the period of time.

Conditions

Pingaccess configured.
