服务器生产环境数据同步报错kettle 导致调度无法正常启动，报错日志如下：
见第二行信息显示：由于内存不足导致，系统无法分配足够内存让调度运行。
解决办法：
可以调节 -XX:MaxPermSize=4096m" 参数，调大点。ps：还有别的参数 可以自行百度一下。如有错误，还请大家指出！谢谢~~

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 2863661056 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
