Server hangs on one time per few days

Server hangs on one time per few days. The situation is next:
player may join, but stucks in 0.0.0 location (PostLogin doesn’t run, because there is teleport to logoff location), no HUD, no keys works (only alt+f4). There are no errors in log. And I even don’t know how to debug this.

Server: dedicated linux with steam.

we have the same problem. Looks like the WorldSeconds variable overflows… we are still looking for a solution other then restarting the server.
Did you solve it?

I thought about some variable with seconds too, but 10 days is 1 million seconds about only - there must be no overflow in float as I understand.

No, I have no solution other then restart server once per week by the Cron. I use monday at 3:30am as low activity time.
