Subject: medm weirdness

Hello,

I am using medm and have noticed something strange.
I have a display with 32 waveforms.
I can open related displays associated with each of those waveforms
(like autoscaled waveform, moving average, etc.)

I noticed that when I open or close a related display ( actually any
display attached to same medm process), all the waveforms freeze.
The IOC is working correctly.

As if none of the monitors were working.
When I open another related display, then the displays update again.

Have you ever experienced this?
Any idea where this could be coming from?

I suspect the PV traffic could be an issue.
Let's assume that I have 40 waveforms with 1200 samples each and a scan
(and updating) rate of .1 Hz.
Is medm overloaded?

Regards,
