Hi Jayesh,

There is no way to get rid of these races....they simply happen in a multi-process app. Simply ignore them as they do not affect the processing.

Bogdan

Hi Bogdan,
Thanks for the reply. I use the fr_timer as 3 seconds in my script and I am also using failure routes extensively to failover my calls to multiple destinations. Can this be a cause for the race event?
Is there anything else that I can look at to avoid this race event?

Thanks for all your help !!

    Hi Jayesh,

    the number refers to a timer list (type):
      0  FR_TIMER_LIST
      1  FR_INV_TIMER_LIST
      2  WT_TIMER_LIST,
      3  DELETE_LIST,
      4  RT_T1_TO_1,
      5  RT_T1_TO_2,
      6  RT_T1_TO_3,
      7  RT_T2,

    4 - is first retransmission timer ,  while 0,1 are final response
    timers.

    The message meas that transaction module tried (in one process) to arm
    again a timer which was just reset (by other process) - it is a race
    between 2 events - re-arming and reseting the timer, Ex: re-arming
    retransmission timer while a reply came and stop retransmissions.

    Regards,
    Bogdan
