当我重启zabbix-agent的时候，zabbix-server的日志中将出现下面的错误 
When I restart zabbix-agent, there will be the following error in the zabbix-server log.
 
18496:20180906:065012.901 [Z3005] query failed: [1064] You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1 [select t.triggerid,t.templateid from triggers t,functions f,items i where t.triggerid=f.triggerid and f.itemid=i.itemid and i.hostid=10259 and]
 
作为一个运维工程师，我认为这是源代码中 SQL 语句 问题
As an operation and maintenance engineer, I think this is the problem of SQL statement in source code.

我在新的环境中测试过3.4.12版本，发现并没有这个问题

I tested the 3.4.12 version in the new environment and found that there was no such problem.

通过有问题的SQL 语句，我追踪到了文件src/libs/zbxdbhigh/host.c中，第2361-2367的SQL语句

Through the problematic SQL statement, I traced the SQL statement 2361-2367 in the file src/libs/zbxdbhigh/host.c

但是我并不懂C语言代码，所以我不能做更多

But I don't understand the C language code, so I can't do more.

最后，祝福zabbix社区越来越好！

Finally, wish the ZABBIX community better and better!
