Boards problem on OXO R4

[Eric]

I just finished instaling a network on OXO with some digital, analog and mixed boards. The test was successful the first week after the installations. But now the problem is that every hour the analog board locks all the ports and make them unobtainable to other extensions. When I go in the details of any of those unobtainable analog extensions from PM5 and exit the interface without changing anything, those particular extensions become obtainable but only for some minutes.

Please, does anyone have met such problem ? I would like some help because it is now two weeks that I'm running that nightmare and as the result analog users are not communicating.

Thanks for your assistance.

Woah, interesting problem. When the boards lock up, is there an entry in the history log? And what do the cards show as when they lock up? Are they still 'present, accepted' in Hardware & Limits > Main Cabinet?
