I checked my inventory and realized I had a first aid case. After removing it my issues were significantly reduced. However, I still get 100000 desync occasionally regardless of my inventory.

I have this issue, and think it might be related to issue number 0001645 (multiple clients connecting to server using same ip). If two computers on my network attempt to play DayZ both get this issue exactly. If only one connects it does not happen.

I have two computers directly connected to the internet and experience a similar issue. The two accounts are able to connect to the same server, but doing so usually results in one or both of the players getting 100000 desync.

At this point both characters can move around, but any actions such as opening doors, looting, turning on torches, or eating are impossible. After disconnecting and reconnecting, some of the users actions seem to have updated. (Attempting to pick up loot will show no affect, but reconnecting will result in the item being in the users inventory.)

I have opened all necessary ports, put one of the PC's on a VPN, and have attempted to connect one computer to the internet through router DMZ settings. None of these actions fix the issue.

The severity of this issue appears to depend on the server. I was able to play for a few hours on a server after trying about 10 others. However, when trying to connect to the same server a day later both users have the issue and can not perform any actions.
