I'm getting a stuttering or intermittent lag with the Phoenix cards in my servers. The problem does not manifest itself constantly; cameras will be fed through the system smoothly but then every so often (maybe every 30-60 seconds) the inputs will stutter/lag for about a second and then return to smooth operation. The stuttering almost looks like it is dropping frames.

No other software is operating in the background except for default OSX operations.

Has anyone else seen this problem? Any ideas to solve it?

Thanks!
