FOSS gamedev and creative worlds

Anybody can't connect after ~ 5 hours of normal work, but server and redis is still running in processes list and server disappears from the list of servers (servers.minetest.net). If i restart minetestserver - it work again ~ 5 hours and the situation is repeated.

"Адрес уже используется" - translated as "Adress already in use" but my autorestart script don't started (it must write in log about this) and server still runing (i use htop) but don't work for players and not allow connect. Before update server and migration to redis from leveldb server always shutdown on errors itself. But now server do not shutdown itself on error and freezes 2-3 times a day and last time without errors.
0.4.12-dev last update about 2-4 days ago from github, debian jessy x86_64, redis 3.0.3 (no errors in log).
*added 10.08. I think it is redis because i install old minetestserver (0.4.12-dev june from github) and still see this errors but server work fine.

My autorestart script:

I have just started experienceing this earlier today as well thus the server crashes

Today all blocks in the world are mixed together, and spawn came under ground in the stones. So i use backup now. I think it is redis because i install old minetestserver (0.4.12-dev june from github) and still see this errors but server work fine.

If the other Minetest session is still running, run "killall minetest"

That will kill Minetest and you can rester it.

amadin, can you tell me the current git commit, and the git commit you used before, is that possible?
You can show a git history with "git reflog".

amadin, which error do you get on 0.4.12-dev june builds too? the spawn error, or the hanging error?

est31: They one Im using on my server was compiled on July 31if that helps any at all

I use 2 versions: 1-10 june and last 2-4 days, i do not remember exactly because in readme.txt no data or number of git commit. Now i fix one warning in redis log, so i must wait 24 hours to see the difference.

Only this strings, server not crashed (shutdown), only freez:
2015-08-10 00:31:03: ERROR[ServerThread]: ServerEnv: Trying to store id=12548 statically but block (-8,2,-11) already contains 49 objects. Forcing delete.

or

2015-08-09 00:30:47: ERROR[EmergeThread1]: WARNING: loadBlock: loading block (-17,-2,-8) failed: LOADING Redis is loading the dataset in memory

In redis log after start was this warning:
Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.

On server version on june from github hang (freezing) after 3-5 hours too but i don't see any errors (server is running but not response), hangs begin after i installed redis. I want to curse because migrate back not work to leveldb or mysql.

@amadin
I seem to remember getting errors similar to yours when using redis. I think I resolved it by adjusting "maxmemory" in my redis.conf and restarting the redis server.

If I remember correctly... my database (all Minetest) had grown to about the same size as maxmemory so needed parts of the map were not loaded into memory when needed by Minetest.

Hope that is helpful :)

Thanks but size of redis database is 800 Mb and i have 4gb RAM, minetest+redis i saw used maximum 2 gb. Fucking redis - i tryed different versions of redis, i tryed different versions of server but always after 5 hours server hangs (freezes) with no errors. On redis load:

But i can't set sysctl vm.overcommit_memory because hoster protect this and i have 4gb ram.
If in redis.conf i set timeout 1800 (0 is default) then after 5 hour it freezes with errors:

If in redis.conf i set tcp-keepalive 60 (0 is default) it is not help. And migrate from redis to mysql or leveldb not supported for my public server with 10-20 players online. I have only one question - who added this redis support in minetest?????????????

Once after ~6 minutes of this errors server was freezed.
Today uptime was 11 hours (when i restart it) yohuuuu!!!! Next time i will not restart it. If it will work without freezing i put here my redis config.

Each map block can contain only 48 entities which include dropped items, mobs, signs, itemframes and once it hits that limit anything over will show an error and be deleted like above... It's an in-game cleanup that keeps servers from grinding to a halt... You CAN increase the number to say 100 but it still means saving more objects in map...
