Ok, so I don't know what's happening with your system, and hopefully somebody can help you with that.
However, I'm going to tell you that my SV8500 just completely crashed after 4-6 days of random troubles. At the end, NTAC told me that some sort of software corruption occurred throughout the years. Maybe due to aging CF cards, maybe MA4000 writing incorrect data to the system - we never found out. Since my backups went back only 5 days, they all had the corruption within them. So the only seeming solution was to reprogram the system from scratch. Imagine that for 2000 users, more or less 24/7 operation, being down for how long? like 1-2 weeks to re-program everything. Not me!!!

What what saved the day eventually was CLIPBOARD. It's a program NEC has and hopefully you also have. If you do, extract all data from the phone system with clipboard, since other backups you may have carry the same corruption. But with Clipboard, you can extract raw data into spreadsheets, and get new CF cards, and using clipboard, you can re-write all the data to new and clean CF cards.
I've done this over 2 nights in a row - I had the system down for like 6 hours each night, but I've recovered my system that way to new and clean CF cards, without carrying over any data corruption.
This is just an advice you may want to follow to have an un-corrupted backup for worst-case scenario.

We always kept 1-2 spare CF cards loaded with generics and ready to go. We also kept clipboard copies up to date and stored safely. On top of that, we did .pdf printouts of every command, just in case. The newer Lynx operating system is not as forgiving as the older NEC proprietary one.
