| I have two tables in a parent-child relationship. Some of the parents have a few children (say a few dozen) and others have many children (over 100,000). I'm trying to run through the parents and pre-calculate some statistics for their children (for example, average, mode, standard deviation, etc.).
All this is working except when I reach a specific parent (#457) the processing just hangs. I ran this through debug and it stalls at the creation of the array for the children.
However, the system would have already processed a similar size array (#30 has 118,000 children) and it seems it's in a loop. Activity monitor says the java process is taking 100%.
Other background. I only save the ec after every 20 updates to the parent records (to reduce write time). And I use ec.invalidateAllObjects() right after saving to clear our memory.
Finally, there is nothing wrong with the data in parent/children of #457 as I can start the process there (or a few parents ahead of this) and it runs fine.
This seems like a memory problem, but I don't get an out of memory exception.
Help on this?
Drew
