Trying to understand why syncNAValue is taking so long sometimes

Hi everyone,

    We run in to this problem every once in a while and can't figure out the cause. Some scripts and batch runs take an extraordinarily long time to run occasionally. We have determined from the logs that the time gap is from using the syncNAValue command. I am new to this position and no one can explain why the command is being called. Originally our understanding was that it syncs all the NAValues within an array to the default NAValue. Now here's my question, why does it then take 30-40 mins on each ldom (we have 14 ldoms) on
