Default Switching Map breaks WebAdmin

Hi.

When switching map, the WebAdmin interface stops functioning. I believe it's due to a failure binding the port to listen on, as shown by this line in the log:
Code:
WebServer DM-1on1-Albatross.WebServer (Function UWeb.WebServer.BeginPlay:0227) BindPort: bind failed
different ports doesn't help, so I'm guessing WebAdmin is opening a new instance before the old one finishes up. Is there any way to fix/prevent this from happening?

Thanks.

What ports are you using for the game server and webadmin? Try changing the webadmin port to something random (like 1337) and see if it helps.

Sounds like a bad mod that holds on to some references it shouldn't, thus preventing the previous level (including the web server) from shutting down at map change.

Does it only happen when switching away from a certain map? Try disabling all your mods and switch them on again one at a time.

It's happening when moving away from DM-Antalus. I haven't tried moving away from another map yet.

I use a bash script to run my server (server-init). Heres what it contains:
Code:
#!/bin/bash
./ucc-bin-linux-amd64 server DM-Antalus?game=XGame.xDeathMatch?mutator=XGame.MutInstaGib ini=UT2004.ini log=ut2004log.log -nohomedir
This is the contents of ut2004log.log. I load the server, login to the WebAdmin then switch maps:
Code:

I am aware the server is somewhat out of date. The newest version gives me "Error closing socket" spam so I downgraded. System is x64 Ubuntu Server.

Have you tried the 32bit version already?

The 32-bit version doesn't work for some reason:

Code:
[email protected]:~/ut2004serv/System$ ./ucc-bin
bash: ./ucc-bin: No such file or directory
[email protected]:~/ut2004serv/System$ ls ucc-bin*
ucc-bin  ucc-bin-linux-amd64  ucc-bin-macosx
[email protected]:~/ut2004serv/System$

Code:
[email protected]:~/ut2004serv/System$ ls -l ucc-bin*
-rwxr-xr-x 1 scan scan  9231832 2005-02-20 11:27 ucc-bin
-rwxr-xr-x 1 scan scan 12868904 2005-02-21 11:42 ucc-bin-linux-amd64
-rw-r--r-- 1 scan scan 14133896 2004-11-23 11:15 ucc-bin-macosx
Nothing out of the ordinary in the relevant files, it seems (unless I'm mistaken, which I could be)

Edit: Okay, I decided an edit might be a bit cleaner than a double post, so I'll just update my progress. ucc-bin was failing miserably because 32-bit compatibility wasn't installed. Whoops! Incase anyone has the same problem, this can be fixed with:
Code:
sudo apt-get install ia32-libs
On Ubuntu Server.

ucc-bin does not seem to have the same problem as ucc-bin-linux-amd64. I can use this for now, but it's still kind of disappointing that it doesn't work 64-bit..

Bumping an old thread :/ .

Anybody found a solution for this? Seems like x64 ucc-bin has this issue.
Any fix applied yet?

Yes, it does.
Installed some 32 compat-libs and it works. But in x64, no luck so far.

If it works in 32bit mode then stick with it. The only real advantage of 64 bit mode is that the server may use more than 2GB (or 4? not sure about Linux, on Windows it's 2) of RAM, but then again all pointers are twice the size, so the server will require more RAM compared to the 32 bit version.

Sorry for bumping. I noticed the same problem - WebServer unable to bind its port - but I'm not using 64bit, in fact, it's certain that my mod is causing the issue.

Code:
Log: WebServer AS-Osaka.WebServer (Function UWeb.WebServer.BeginPlay:0227) BindPort: bind failed
netstat reports that the port is still being listened, so I guess it's exactly what Wormbo stated here:

What kind of leftover references would be responsible for this?

I do hook myself into the GameStats class in order to track game events, creating my custom GameStats class instance when the match starts and passing all function calls to the original GameStats if present.

I will try cleaning the references it uses later on today, I just wanted to ask for maybe other ideas here, other admins and mod authors might find this useful.

EDIT:
My fix didn't work, I still have the BindPort failure, so the question remains: what kind of references could prevent the game from shutting down the webserver?

EDIT #2:
Solved by resetting a static reference to the Mutator to None upon server travel.

He probably assigned an actor from the current level to a default class property somehow and fixed his problem using the Mutator.ServerTraveling() event.
The engine only cuts the "referencing tree" at the level, so if another reference to an actor from that complex construct is created, the entire level is still referenced and won't be garbage-collected on map change.
