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

Native memory allocation (malloc) failed to allocate 137363456 bytes for committing reserved memory.

An error report file with more information is saved as:

/usr/local/tomcat/webapps/hs_err_pid31202.log

解决方案：
cd 到tomcat的/bin目录下，找到catalina.sh文件添加以下代码
# OS specific support. $var must be set to either true or false.
JAVA_OPTS="-server -Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=256m "

重启tomcat 就好了！！！
