    Do U Revit: Revit Server is Desktop no more

    Well, we finally gave up. Reluctantly.
    Our Windows 7 setup seemed to be working just fine. However we were plagued by Revit crashes following a successful synchronization with central at the location connected to the Local server. At first we thought bandwidth was to blame so we upgraded our connections by installing business cable at the location with the least bandwidth, fully dedicated to Revit Server to Server traffic (2Mbps up, 12Mbps down). We left the previous connection in place to other uses such as VoIP, VPN, etc. In the main office we left the bonded T3 (3Mbps up, 3Mbps down) alone but removed traffic shaping to make sure Revit Server received maximum capacity.We also configured the Revit Servers with their own public IP address so traffic was outside of VPN and thus not slowed down by encryption. The servers are protected and not accessible from outside the network through various router rules and protection safeguards.
    Unfortunately this did not eliminate crashing at the user’s desktop. Our next experiment was to switch the Central and Local servers around to see what effect this would have (not the physical machines). We ended up with the Local server in our main office with around 6 people working on server-based projects and 2 at the remote location saving directly to the Central server. Through our upgraded connection, we could now create central files through the Local server, which was not possible in the past. So we know that at least bandwidth cured that issue. The crashing unfortunately followed the Local server and users in the main office started experiencing this crashing following a successful SWC, 90% of the time. Go figure.
    Our next step was to install Windows Server 2008 SP2. We did this on the Local server first. Lo and behold, the crashing ceased even with the central server still running Windows 7! At this point we don’t know exactly why this is happening and gave up on our endeavor. We still think Windows 7 should do the job but somehow, there’s some setting somewhere that is causing Revit to blow up. Or maybe WS2008 is more efficient at handling limited resources such as RAM? But why would Revit crash, with no debugging info. available?The machines we’re using as servers are low on RAM so who knows? The journals do not point at the culprit and Revit mysteriously crashes after successful saves (servers keep running fine, projects do not corrupt and the Revit Server administrator reports the saves are successful), so at this point we bow our heads and wave the white flag. Bummer.
