Hi, everyone.

     I found a issue in MQX4.1. When I use the DHCP function to get IP and DNS that's no problem. When I plug out the ethernet cable, My APPI unbind the ipcofig and use the deafult IP address.But the "ipcfg_unbind(BSP_DEFAULT_ENET_DEVICE);" blocked untill the WDG reboot. I debuged it and found in the "uint32_t DNS_remove_slist_entry" function free the illegal memory. The following information is the

DNS_SLIST_STRUCT  *temp_ptr

data.
