SegmentationFault - Raspberry Pi

[Minepi]

Can you try downloading a new build, see if it still crashes, and provide the build ID please.

I downloaded a new build : MCServer Linux armhf #46
Will try tomorrow if the new build is working, so there is probably nothing to fix... I mean tomorrow because I live in France, so it's not the same hours.

Oh. I thought you were not because of the posting hour of MCServer.

My build is working but I can't put the server in survival for all players by default using the web interface.
Also there is no animal and monsters doesn't seems to see me/aren't moving fluently.
The far map is also loading and I can see the lava and threes are loading.

Monsters and animal weirdness is normal, and we're working on fixing it.

Oh ok.
But for the creative activated by default I can't change it by the web interface, what do I need to put in settings.ini to enable the survival mode?

[xoft]

The gamemode is set on a per-world basis, so you need to edit the world.ini of the world for which you want to set the gamemode.

I am also experiencing a segmentation fault on a Model B Raspberry Pi with Raspbpian (MC server hardfloat). However, it occurs immediately when someone logs in. If no one logs in, the server runs fine.

I tried compiling by following the Linux instructions exactly, however that failed at the cmake step at 23%. I will post my exact compilation issue in a new thread.

I'm having a similar problem with both the precompiled server on my Pi model B+ (512Mb) and a server compiled on my Pi. The server appears to start up OK and I can command "help" and get a list of MCServer commands, but as soon as I join the server from Minecraft 1.8.3 running on my Mac, the server quits with a segmentation error.

I first used raspi-config to reduce the Pi graphics memory to 16 Mb. I then followed the Wiki instructions for compiling MCServer on my Pi, first issuing the Raspberry Pi commands and then the Linux commands. There were a number of "not found" messages during the "make" process but it appeared to work. I am running RASPBIAN (Debian Wheezy) on my Pi on a 16GB SD card. I am new to both Minecraft and Raspberry Pi so I wonder if there is some configuration issue on the Pi or on Minecraft on my Mac that I am missing. Shouldn't this work?

I have started the server twice and had apparently the same result. The first time I started the server I got many more messages than I got the second time. The messages I got the second time, and the errors I got after trying to join the server, follow. I also included a directory listing after the errors:

That looks like a genuine crash. Could you follow this guide to provide as much information as possible? https://forum.cuberite.org/showthread.php?tid=631
Thanks.

Thanks.

Thanks for responding. I followed the reporting guide as much as I could and attached file mc_issues.tar with the info I collected. I didn't have a core dump file so I tried the "Live Analysis" and included the gdb.txt file (the crash.txt didn't get created).

I then tried to start the server in the usual way from the shell prompt. It started up OK. I then joined the server from Minecraft running on my Mac... and it worked! I was able to move around, fly, blow up TNT and it didn't crash! I quit the game and then rejoined the server without problems. Could running gdb in the "Live Analysis" have fixed it?

Thanks again.

P.S.
I tried to attach the mc_issues.tar file but the forum server gave an error saying that the file was too large (larger than 1024 kB). The MCServer file I included is 7.5 MB so it didn't work.
