Hi,

I have had the same UC520 for well over a year. I have never seen that issue. I dont know if there are crash logs on the flash that Cisco may be able to assist you to pull them off and understand if it was a hardware or software issue.

Are you back up and running now? If you need any help let me know, as I have performed this install from scratch many many times.

Thanks

Brian
