Hello again Mike,
Concerning this issue, do you have an example link? Also do you have progress pages enabled? Also which version are you currently running? Have you attempted to open the file in notepad (then scroll to the end)?
Just to give everyone an update. The issue was with the heartbeat btw both web gateways. They were not synced, it required a re-boot of both servers and then the heartbeat was fine, I continue to monitor this and since the reboot, probably 8 weeks ago, we have not had any issues.
