Campaigning Issue

Hi, 

I got an issue while running the campaigning for writing the data into Custom Object, please kindly review and let me know if you have any idea if that's really some limitation around Campaign feature. Please see the issue details below:

I got 5000 contacts that have been filtered by segment, normally we just use Reschedule Point to trigger Object Event Handler, once it been triggered, it will take out few of contact fields and write into certain Custom Object, so normally it should generate 5000 records in it, but it stuck at 2000~2500, all the time.

As I can make sure the handler is correct, which make me wondering is that because the Campaign itself has some sort of limitation that stuck the process when it hit certain amount when writing into object, such as 2000+ records, please help :)

Warm regards

Sven
