While troubleshooting the other issues, something odd happened when I left everything and walked away for a bit. I had 3 characters logged in, each in different chunks. 2 of those characters crossed multiple chunk lines moving around the world. One of them left Bordinar's Cleft, then turned around and went back in. That's when I walked away.

Sometime in the next 12 minutes (oddly), everyone got booted. Here's the log from the point my 2nd toon left Bordinar's Cleft to 3R then went back:

Enter 3R

Then, 7 more minutes and boom, die die die.

Clearly, the 192.168.1.108 (client #2) is at fault here, because notice nothing about it disconnecting from the re-entered Bordinar's Cleft, nor BC itself ever shutting down was mentioned. Almost like BC shut down/crashed quietly (no logging) and tore everyone else down.

Maybe try leaving a chunk, turning around and heading right back in may reproduce this bug.


Server never crashed, no errors, just everyone online got booted. This is with current SVN (614).

Also, you mentioned you had 2 other clients connected, but they are each using 2 UDP ports (or at least, they disconnect from 2 ports) and had been sitting around not changing chunks. Is this normal to keep 2 ports per client open?

At present, it is. One to the WorldServer, one to the ChunkServer. I am unclear if this is a limitation with the client(?) and how it manages connections, or if it's just a weird design that never got the attention it deserved.

If you do the math, 100 players in 100 chunks (200 ports), moving around with 5 minute timers to shut down, leaves a lot of open ports to the world server. I don't think that's right, but may be what we're stuck with. Other emu's don't do it this way (that I'm aware of) so I'm hopeful.

Btw, just like my day job and everything else, I performed the exact same steps as above, and the connections did not disconnect this time. I am 0 for 2 today.
