Certain conditions might produce error messages similar to the following in the core file/tmm.log: -- RVAvpBigIP01 notice RIP=0x8cc872 -- RVAvpBigIP01 notice session_process_pending_event_callback ERROR: could not send callback to 192.168.96.27:504 - 192.168.96.28:443 ERR_NOT_FOUND.
Traffic disrupted while tmm restarts.
This occurs because of a race condition, one between the HTTP and APM-related profiles, for example, during which an APM-profile-related action completes after the HTTP-profile closes the connection. Note: Logs that occur without a core are not a symptom related to this issue.
The race condition that occurred has been fixed, so no APM-profile-related actions complete after the HTTP-profile closes the connection.
