Problems with Cyclone IV and DP83848C

Dear all, I've made my own board of Cyclone IV EP4CGX110CF23C7. And i want to make a ethernet module with DP83848C which is surpported by the TSE core.
However, when i have completed my SOPC system and downloaded the nios program, it seems that something wrong happened to my program and i am confused
by this problem for several days. When i run my project as NIOSII hardware on NIOS SBT v12.1, the nios ii console displays as following:

InterNiche Portable TCP/IP, v3.1

prep_tse_mac 0
Your Ethernet MAC address is 00:16:36:fc:14:2d
Static IP Address is 192.168.1.234
prepped 1 interface, initializing...
Netinit: calloc failed getting buffer 17
inet startup error: unable to initialize net
panic: IP
dtrap - needs breakpoint
ip_exit: calling func 0x9e7a4

Here are some attachments of my program.
PS: 1. I turned off the DHCP and set the board IP address 192.168.1.234.
2. I created the program from the template Simple Socket Server.
3. There is no NAND flash on my board and i set my board MAC address 00:16:36:fc:14:2d
