panic: tcp_out - packet ptr underflow

[Altera_Forum]

I'm using Nios II 8.1 IDE  

 I've got a Custom CPU board with a Cyclone III and the National Semiconductor triple speed ethernet chip. I have the Niche Stack license.  I've successfully run code with the simple socket server as the basis.  For my final delivery I needed to add the Remote Config capability, so I "married" the two features (I tried this first on a NEEK development board and a subset of my code and was successful). The way I did this was make a project based on the "Remote Configuration" and added the Simple Socket Server Code I needed. I start the ssstask after the rctask - code snipet follows:   /* Create the main remote configuration task. */  TK_NEWTASK(&rctask);    printf("\nSimple Socket Server starting up\n");  /* Create NicheStack Tasks. */  TK_NEWTASK(&ssstask);  TK_NEWTASK(&EnetTask);     /* Application Specific Task Launching Code Block End */    /*This task is deleted because there is no need for it to run again */  error_code = OSTaskDel(OS_PRIO_SELF);  alt_uCOSIIErrorHandler(error_code, 0); # ###############################################  My new code runs just fine when I run from the IDE.  When I burn the program into flash and I try to connect to the server I get the following error:  ****************************************** panic: tcp_out - packet ptr underflow  dtrap - needs breakpoint netclose: closing iface Altera TSE MAC ethernet   ******************************************  A bit more information. I do have other tasks and here are the priorities I've selected: # define LOGIC1553_PRIORITY 10# define SENDENET_PRIORITY 12 //Send 1553 Data# define VFD_PRIORITY 14 # define SSS_PRIORITY 4# define TEN_FOUR_ENET_PIO 13# define DISCONN_CHECK 15 //// ADDED for remote configuration# define REMOTE_CONFIG_PRIORITY 5 // was 4 and hard coded  My simple socket server is Priority 4  Can anyone help me ?
