| ENC28J60 + 18f452 reset issue |

Hi,
I'm trying to get TCP/IP working on my PIC-WEB.
this is how my ccstcpip.h looks
| Code: |
//////////////////////////////////////////////////////////////////////////////
//
// ccstcpip.h - Common code shared among all Embedded Internet/Embedded
// Ethernet tutorial book examples.
//
// If you are using a CCS Embedded Ethernet Board (labeled PICENS, which
// has an MCP ENC28J60) then define STACK_USE_CCS_PICENS to TRUE.
//
// If you are using a CCS Embedded Internet Board (labeled PICNET, which
// has a Realtek RTL8019AS and a 56K Modem) then define STACK_USE_CCS_PICNET
// to TRUE.
//
//////////////////////////////////////////////////////////////////////////////
//
// 10/25/06
// - Added STACK_USE_CCS_PICEEC
// - ExampleUDPPacket[] UDP header length fixed
//
// 2008.12.20 - JGSCHMIDT
// - added STACK_USE_CCS_OLXMINI for Olimex Mini-Web board

The problem is: afer StackTask has been called a few times the PIC will reset. Am I forgetting something? I used http://www.ccsinfo.com/forum/viewtopic.php?t=37139 as an example for my code.
