Q:

Could not ping, broken pipe in MariaDB Drizzle JDBC

I have an java application which uses mariadb server. From java, drizzle jdbc is used for connecting the mariadb server. Sometimes, I got an error, broken pipe.
I don't know why this error occured, its root cause.
Iam using ubuntu12.04, latest drizzle jdbc driver(1.2) and mariadb 5.5.29.
Please see the error log :
