Requests cannot be released during the upgrade

Hi guys,

During an Upgrade that is currently on Preprocessing stage, a developer needs to release an urgent change. We are not able to proceed with the Upgrade due Networking issues related to IP Multicast (Kernel 740

I tried running tp unlocksys and tp unlock_eu, both returning code 0, but still getting this message?

Do i need to restart the instance or should I modify UVERS table in order to release this request?

Thanks for your advices!
