Hi,
I have spent the last few hours getting to the bottom of this problem. There seems to be a limit to the number of addresses that the synch manager can successfully synch per customer. We have a number of customers with addresses that exceed 250 addresses.
If any update was made to one of these BP's the synch manager was crashing with no error message. Running SQL Profiler showed that the synch got about 250 or so addresses in before crashing.
A bit of experimentation (deleting addresses) has shown that the maximum for my setup seems to be about 250 addresses per customer.
As I lowered the number I also received an error message relating to Out of memory (this is a 4GB RAM server).
My course of action will be to make sure that we have a maximum of 250 addresses per BP (unless anyone else has a better course of action), but I just thought I would flag this in case anyone else was having this problem.
Martin.
