Time to time server crashes. But a strange thing is, that crashes java but for the server and no crash logs appear in the console.
Here are java error logs: http://pastebin.com/yMQ038HP
Seems that lots of server owners have similar issue, hope it can be fixed..

P.S: Players say, that crashes took place only when one player tries to hit another, and they are members of rival clans.

@ZerekZarson @jkobus
Are you guys using SQL or Sqlite? I believe this issue may be just with Sqlite dbs.

@Kainzo
Using Sqlite. And is there any way to convert Sqlite database to sql?
I've seen that only simpleclans2 supports conversion, but it's database structure is different.

Try to set auto-war-start in your config to false, probably it will fix this temporary

cannot reproduce the issue with the latest version. using mysql.

Jup, only happens with sqlite, as the jni implementation of the sqlite-jbdc library doesn't include null checks -> jvm crashes

@p000ison
Thx. Such a simple solution, but it seems that it really helped :D
(changing auto-war-start to false)

+1; happens on certain players only and is reproducible even after server restart on the same player.
Player nickname: "Minecraftowykolo"

I have found the exact cause of this issue. When a player who is the leader of a clan, is killed. the server crashes.

I'd really like this to be solved. No clue what to do about it.

will the creator(s) of the plugin see this?

Thank you so much !
