[c-prog] Help in finding crash cause in given peace of code.

[Ravi Mishra]

Please help me and provide your suggetion for finding the cause of crash
dump.
I am providing the pease of code where dump is occur.

The problem is that that crash comes after a random time(some time in 5hr
asnd some time in around 11 hr).

so that is very much difficult to track this dump.

Here is the piece of code.
===========
void macHandle_CongestionIndication(VTASK *vtask,
AISUE_PRIMSAISUE_tnl_congestion_ind* congInd)
{
   VARIABLE_STR* var = (VARIABLE_STR*) vtask->var;
   MacCommon* mac = &var->mac;

   if(mac->stepsOfCongestionCounter == 0)
       return;

   if (congInd->congestionStatus ==
no_congestion_AIS_IEsAIS_TnlCongestionStatus)
   {
       if(mac->congestionCounter[congInd->macDflow] > 0)
       {
                 if(mac->congestionTimerInstance[congInd->macDflow])
                 {
                         timerStopInst
(mac->congestionTimerInstance[congInd->macDflow]);

mac->congestionTimerInstance[congInd->macDflow]=NULL;
                 }

           mac->congestionCounter[congInd->macDflow] -= 1 ;
         if(mac->congestionCounter[congInd->macDflow] > 0)
         {

 mac->congestionTimerInstance[congInd->macDflow]=timerStartInst_ms (vtask,
MAC_CONG_CTRL,mac->congestionTimerDuration, (void*)congInd->macDflow);
/*YGA_17-Oct-08_60523_Changed_timerStartInst to timerStartInst_ms*/
         }
      }
   }
   else if ((congInd->congestionStatus ==
delay_build_up_AIS_IEsAIS_TnlCongestionStatus) || (congInd->congestionStatus
== frame_loss_AIS_IEsAIS_TnlCongestionStatus))
   {

if(mac->congestionCounter[congInd->macDflow] <
mac->stepsOfCongestionCounter)
      {
                if(mac->congestionCounter[congInd->macDflow] >0)
                 if(mac->congestionTimerInstance[congInd->macDflow]){
               timerStopInst
(mac->congestionTimerInstance[congInd->macDflow]);

 mac->congestionTimerInstance[congInd->macDflow]=NULL;
                }

         mac->congestionCounter[congInd->macDflow] += 1 ;


 mac->congestionTimerInstance[congInd->macDflow]=timerStartInst_ms (vtask,
MAC_CONG_CTRL,mac->congestionTimerDuration, (void*)congInd->macDflow);
/*YGA_17-Oct-08_60523_Changed_timerStartInst to timerStartInst_ms*/
               }
      }
   else
   {
      Printf("ERR_FATAL\n");
   }
}



Thanks in advance
Ravi
