The above command displays a lot of information but we are interested in the most repeating socket ID. In
the above example it is 0x8. To look into what does this socket means the following command can be used
in Dshell:
Working: [Kernel]->ipc_socket_info 0x8
ipc_socket_info
Socket 8:
LocalSocketID = 0x8, localidx = 0x8, Local_address = 0xf400041
RemoteSocketID = 0x8, Remote_Address = 0xf400042
QnumBufs = 1, NumBufs = 1588, seqSent = 1588, seqRecv = 1588
USRnumBufs = 1, State = 0x3, OptionFlgs = 0x0, priority = 1
blk_timeout = 0, LingerTime = 0, RxQ_Full_Threshold = 65536,
RxQ_Numbuf_Threshold = 128 congestion = 0, SockMask = 0x100,
SockMsbs = 0x0, use_sw_buf = 1
remote_cong = 0, init_done = 13, sem_use = 0, alignmentSpace = 0
Task id = 0x67f3c10 (tCsCSMtask), LastTimeStamp = 1046954691
recvErrs = 0, txCnt = 1588, txErr = 0, eagainCnt = 0
xoffsent = 0, xonsent = 0, xoffrecv = 0, xonrecv = 0, congcount = 0
value = 8 = 0x8

The output of the above command shows that tCsCSMtask is the one consuming this socket.
Older versions of the code might not show the task name in the task ID so the following command can be
used to find out the tasked:
Working: [Kernel]->ti 0x67f3c10
