    Clients Spontaneously Disconnecting from FMS 12

    LenLevin

      I have a client with FMSA 12.0.6.600 running on a new MacPro, 10.9.3. The server is hosting a 46 data file, 25Gb EMR system. There are 25 systems connected to the server from time to time. Over the past few months, for no particular reason clients are spontaneously disconnecting from the server. The clients are all Macs running FMP 12v5. Most are running 10.8.5 and a couple of newer iMacs are running 10.9.3. The client systems are all set with static IP addressed, power settings are turned off with the exception of display sleep. On the 10.9.3 systems. App Nap for FMP is disabled. The disconnects happen at anytime, there is no particular pattern to when it happens. It happens while the the EMR is being used.

       

      Has anyone seen this behavior? Suggestions, experiences, solutions would be greatly appreciated.

       

      Thanks.

          Clients connected through wired ethernet or wifi?  Do the disconnects happen in groups of users or completely random across users / times?

           

          Either way it seems to indicate an instability on the network.  Could be bad cabling, a failing switch, or it could be other activity on the network.  If VOIP is running on the same network and the QoS settings are aggressive it can reduce the bandwidth for FM and cause delays long enough to make FMS think the clients have disconnected.

          Same can happen if bandwidth is used heavily for say Netflix streaming...

            Thanks for the reply.

             

            Would never run such a system over WiFi.  Totally random.

             

            Nothing else has changed.  Just the new server.
