Opened: Jan 17, 2017
Severity: 2-Critical
The TMM may crash when search through an external data-group that has at least one value with empty value.
Traffic disrupted while tmm restarts.
For example, this occurs if data-group is defined as follows: the key for network 10.40.0.0/13 has no value: network 10.0.0.0/9 := "network 10.0.0.0/9", network 10.40.0.0/13, network 10.10.0.0/17 := "network 10.10.0.0/17", A search in the data-group above with -value or -element options where at least one of the result records has no value will most likely result in a TMM crash.
Make sure that every record in the external data-groups has a value.
Searching values in an external data-group where result will contain at least one value with an empty value no longer results in a TMM crash. A -value search will yield an empty string for the records that do not have a value.
