Hi Nilson,

When you say it is dropping frames, can you be more explicit?  Can you tell where the frames are being dropped, i.e. between the detector and the IOC, or in an IOC plugin?

What plugins are you running in this IOC?

Are they configured with blocking=Enabled or Disabled?

What queue size are the plugins using?
