I am testing Connection Message Shuttle for a Connection 10.5 to 11.5 migration of about 5K users and 20K messages. Testing, it has been doing great until about half way through I start seeing warning messages: "Target Connection server's drop folder is full - slowing down SMTP transport.". This also results in and error in the log included below. Seems like the target system is getting too busy. Should I do something to throttle the transfer or just run multiple passes?
Here is the errors I see logged:
[Thread 009], [18/08/06 10:07:34], (warning) Target Connection server's drop folder is full - slowing down SMTP transport. New send delay(ms)=100
