When the peer/clientside/serverside iRule contains parking commands, or in NTLM profiles (which utilize parking commands), tmm might core upon connection reuse.
Traffic disrupted while tmm restarts.
1. The iRule used in peer/clientside/serverside contains a parking command. 2. The connection is reused. This might occur in OneConnect configurations, for example. In configurations that do not have parking iRule commands, this issue might also occur when the NTLM profile is in use, as the NTLM profile also utilizes parking. Note: The NTLM profile might be deployed automatically if you are using a SharePoint iApp.
Do not use parking commands in cases where the system might reuse the connection. If the issue occurs with the NTLM profile, do not use the NTLM profile, if possible.
When the peer/clientside/serverside iRule contains parking commands, or when using NTLM profiles that utilize parking commands, tmm no longer cores upon connection reuse.
