We recently learned from one of our customers that the UC110 VM Module goes off line for no obvious reason. They stated that it was only about 3 or 4 times over the last 5 or 6 months, but they decided to share because they thought it might be a hardware or software issue. We investigated and found that this could happen if a broadcast message is sent out to 20 or more users. We explored with the customer and they stated that they are aware of the feature, but have not shared it with the users. They checked with a few that my try something on their own and that came back negative. My tech is checking to see the exact versions of the IPO R8.1 that is running on the system, but I thought I should share this matter with the IPO community to see if any of you have experienced this before and if so a possible resolution.
