TMM can crash when an IP fragment is received and packet filtering is enabled.
Traffic disrupted while tmm restarts.
This issue can occur when packet filtering is enabled and an IP fragment is received on the non-owning TMM. To determine if packet filtering is enabled, then the packetfilter setting can be queried by using the 'tmsh list sys db packetfilter' command.
Disable packet filtering.
When packet filtering is enabled and an IP fragment is received on the non-owning TMM, TMM forwards the IP fragment without issue.
