environment

canal version 1.1.3
mysql version 5.7.20

Issue Description

使用Canal Adapter RDB 从RocketMQ接收消息写入数据库，运行一段时间后程序退出，错误信息如下： Java HotSpot(TM) 64-Bit Server VM warning: Attempt to protect stack guard pages failed. Java HotSpot(TM) 64-Bit Server VM warning: Attempt to deallocate stack guard pages failed. Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007efd17acf000, 12288, 0) failed; error='Cannot allocate memory' (errno=12) #

There is insufficient memory for the Java Runtime Environment to continue.

Native memory allocation (mmap) failed to map 12288 bytes for committing reserved memory.

An error report file with more information is saved as:

/data/datasync/canal_sync/bin/hs_err_pid499531.log

服务器内存是足够的，不是由于服务器物理内存不够导致的调整bin/startup.sh中jvm参数没有效果
