Hi FS, nice job with a good release. Hits appear to be much improved, and the maps look great.
One major problem we are having at the moment, is we are getting a consistent segmentation fault on 4.2.
The crashes produce the following:

Hit: 17 16 8 19: Glock.HIGH hit beanrofllmao in the Right Arm^M
eceived signal 11, exiting...^M
----- Server Shutdown (Signal caught) -----^M

Hit: 9 13 9 19: *X|pcc.* hit cankpt in the Legs^M
eceived signal 11, exiting...^M
----- Server Shutdown (Signal caught) -----^M

Hit: 10 0 9 8: heh hit Loul|ahts in the Legs^M
eceived signal 11, exiting...^M
----- Server Shutdown (Signal caught) -----^M

Hit: 0 14 9 19: `hG*7* hit heh*9* in the Legs^M
eceived signal 11, exiting...^M
----- Server Shutdown (Signal caught) -----^M

These are all separate crashes. We are getting between 4 to 6 segfaults a day, all pretty much on a full server (close to 24/24).
5 have crashed on tp, 3 on uptown, 3 on abbey, and 1 on algiers. All 3rd part maps have been removed to see if that is an issue. In addition, ut4_commune.pk3 has also been removed. bot_enable is set to 0 for the majority of the crashes (I believe all, but I cannot verify that from the logs). Also auth_enable has always been set to 0.

Right now that is all we can identify from the pattern. Any other server admins running on linux experiencing similar crashes?

I am not sure if this is related, but just wanted to confirm if you saw the big yellow banner announcement at the top of the website that says this:

Quote

Urban Terror 4.2: Game servers admins, please set auth_enable 0.
There is a mismatch between the version of QVM and the engine. It breaks the auth, and it can crash your game server after a while.

Ty nitro. Was just going to edit this post to mention that important point. We have set auth_enable to 0 since the beginning.

Yep we're aware of this huge issue and trying to detect and fix it. Thanks for your patience!

[moonq3]

Cool, thanks Barbatos. Let me know if you need any logs for debugging or if I should put gdb on it.

Hi,

Any rough eta on this fix Barbatos?

For the moment we are keeping our 4.2 server going, which is fairly popular, but with every crash it is hurting our 4.2 playerbase.

Also, from what I can tell it is NOT in the server binary. I think it is in the new vm's, because I'm running your latest github checkout (@ PROTO 68) for our 4.1 server, which is solid as a rock. So my guess is something in the qagame code is contributing to this rather than the server binary itself.

We (think) that we've finally found and fixed the bug yesterday, it was due to the hitmesh (that's why the servers always crash after a hit/kill). We will push the next release asap after a few testing sessions.

gg, ty Barbatos :)
