LocalPool: Full size is 64, remaining: 64
In socket queues: 0 Not queued: 0:
DMA queues: 0
In the above two outputs it seems that the control pool is stuck and the socket queues are incrementing. In
order to find out which task is using these queues we need to look at the socket information.
To look in detail about these pools the following commands can be used in Dshell:
• Ipc_urgent_pools_detail number
• Ipc_control_pools_detail number
• Ipc_normal_pools_detail number
• Ipc_jumbo_pools_detail number
• Ipc_local_pools_detail number
The above commands have an option to specify the number of sockets to be displayed in Dshell. If no
number is specified then it will display all the sockets in use which can be real problem in case of thou-
sands of sockets being used.
