Issue is caused by an interesting race condition with XMSG messages and indeed, the RADIUS task plays some role here as well. Issue is stimulated with use of UCM / EM. At a customer’s locations it can happen, once a day, once a week, or a few times a day, to several a week, taking into the account where the PSS is located in the customers network.
