When TMM is crashing abnormally, the restart procedure can lead to following crashes of other processes in the system.
The crash of the other processes has no impact on the system, as the fact that TMM already crashed is the main impact. There is evidence of the other processes crash, since there are core dump files, so it is raising concerns about why several processes crashed and leads to customer escalations.
Relates to cases in which TMM crashes abnormally as a result of other issues.
The non-TMM processes are shut down more gracefully and are not crashing with core dumps during the system restart.
