I have build B3083 on my CP1400 and it had it's issues were I needed to reboot the device monthly otherwise, when I would log into the GUI and navigate the logs or anything it would core and restart the sfwd. So rebooting it monthly is a workaround. Was given a custom build B3105 and while it should promising results, the GUI core still occurs so back with R&D. Hopefully one day before am out of support in 2024 they will get it right.
Point here, open a TAC and see if there is a custom firmware and maybe you'll have better results. As B3083 is very buggy.
