when start a run, it bring the mtransition process and I guess the server try to talk to the
client, then it fails and the frontend application get killed since not response.

it gets
[midas.c:8423:rpc_client_connect,ERROR] timeout on receive remote computer info: 
[midas.c:4880:cm_shutdown,ERROR] Cannot connect to client
"feTPCPacketReceiver" on host 'tpcdaq0', port 35865
[midas.c:4883:cm_shutdown,ERROR] Killing and Deleting client
'feTPCPacketReceiver' pid 27250
Client feTPCPacketReceiver not active


what does this error mean? :
11:03:42 [Logger,ERROR] [system.c:563:ss_shm_close,ERROR]
shmctl(shmid=7274511,IPC_RMID) failed, errno 1 (Operation not permitted)
