Io 异常: Connection reset；Io 异常: Got minus one from a read call；IO 错误: Connection reset by peer, Authe

报错信息：
1.
IO 错误: Connection reset by peer, Authentication lapse 0 ms.
搜索网上有些回答说
是JVM随机数造成的延迟问题。
看下kettle控制台所属服务器的$JAVA_HOME/jre/lib/security/java.security文件中将命令securerandom.source=file:/dev/random
改为：securerandom.source=file:/dev/unrandom
但是我查看我服务器的这个文件中本来就是securerandom.source=file:/dev/unrandom。
2.
再运行一次发现报错有变化：
IO 错误: Got minus one from a read call
再跑一次的话报错还有变化：
Io 异常: Connection reset
第二个报错像是连接中断的报错，
然后去服务器长ping这个数据库服务器核实一下会不会丢包
命令：ping IP -c 50 | awk '{ print $0"\t" strftime("%H:%M:%S",systime()) } ’
发现会有百分之二的丢包概率

首先将丢包问题解决丢包
在kitchen.sh文件的最后一行中的Java 命令行中增加参数：-Djava.security.egd=file:/dev/…/dev/urandom 试试

发现报错基本维持在一种报错，
此报错考虑为数据库连接数超了的问题，联系对方数据库dba核查，但是数据库连接数没有超，
最后发现为
此服务器ip不在数据库的白名单中，
dba将此服务器ip加到数据库的白名单中，发现正常，没有报错了。
完成。
