TMM crashes and generates a core file under unknown conditions.
TMM crash and core. Traffic disrupted while tmm restarts.
The conditions required for this issue to occur are not well understood, but might be related to a MCP message handling failure (during virtual server creation) in an AAM with LTM configuration. The issue might be related to an unsupported configuration, as follows: The BIG-IP system does not prevent you from configuring a server-side iSession profile and a OneConnect profile on the same virtual server. This is not a valid configuration, however. Virtual server configuration should allow either a server-side iSession profile or a OneConnect profile, but not both.
Correct the misconfiguration (specifically, OneConnect and iSession being mutually exclusive features), and try the operation again.
