Getting hardfault in _nx_packet_release function

[kaushaleinfo]

Hi all, I am using stm32f205 mcu and using threadx, netx 6.2 version, Random time I am getting hardfault from _nx_packet_release so I did depth debugging and found where exact it is generating hardFault, So it is generating while / Update the links of the adjacent threads. / in _nx_packet_release function,

/ Determine if there are any threads suspended on the block pool. / thread_ptr = pool_ptr -> nx_packet_pool_suspension_list; if (thread_ptr) { / Remove the suspended thread from the list. /

        /* See if this is the only suspended thread on the list.  */
        if (thread_ptr == thread_ptr -> tx_thread_suspended_next)
        {

            /* Yes, the only suspended thread.  */

            /* Update the head pointer.  */
            pool_ptr -> nx_packet_pool_suspension_list =  NX_NULL;
        }
        else
        {

            /* At least one more thread is on the same expiration list.  */ 

            /* Update the list head pointer.  */
            pool_ptr -> nx_packet_pool_suspension_list =  thread_ptr -> tx_thread_suspended_next;

----------->>>> from below line code it is generating a hardFault, <<<<------------------

            **/* Update the links of the adjacent threads.  */
            (thread_ptr -> tx_thread_suspended_next) -> tx_thread_suspended_previous =
                thread_ptr -> tx_thread_suspended_previous;**

Mostly it is generating after discover DHCP packet, Could you guys tell me why this is happening or where should I look?

It sounds like memory corruption or illegal usage of packet. Could you try to disable all logics from application and run DHCP only? See if the problem is still there.
