we have a C3500 with DM0 running firmware v1.98. this was installed last summer and recent began having this issue.
we’ll notice when a button is pressed there is a lag of a second or two before the Surface responds.
Over the next few minutes this time lag increases to several seconds and longer. we’ve timed one lag at 4 minutes.
During this time audio processing continues to occur although no changes can be made on the surface.
Eventually the surface becomes completely non-responsible and we have to power cycle it.
The DM0 shows no errors.
Once the reboot completes the Surface operates normally. It has been a few minutes to a few hours before the next event occurs.
This started about 3 weeks ago. There have been no changes to the equipment connected to the control network.
Log have been sent to A&H and are awaiting their review.
Perhaps has anyone else seen this behavior?
I would suggest checking two things. First, make sure you are using a shielded ethernet cable that is Cat5e or higher rated. You must use shielded cables to work reliably. Second, double check your network settings. If there is a conflict or if devices are set to DHCP and there is no DHCP server located, it can definitely cause connection issues.
