Hi Harsha,
Thanks for your reply. Yes, I've come across this before where the Webi server has run out of memory or failed in some way and restarting it has fixed the problem. However, this is not the case this time. I tried restarting the Webi server, with no luck. The Rich client also connects fine.
You can also get this error when the Webi client is down.
Regards,
Jonathan
