This is a late answer but, I had faced same issue. It's due to improper configuration for c3po.

Please use below c3po configuration:

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driverClassName}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />

        <property name="checkoutTimeout" value="30000" />
        <property name="idleConnectionTestPeriod" value="30"/>
        <property name="initialPoolSize" value="10" />
        <property name="maxIdleTime" value="30" />
        <property name="maxPoolSize" value="100" />
        <property name="minPoolSize" value="10" />
        <property name="maxStatements" value="10" />

</bean

This fixed for me on the servlet-context**.xml** adding maxidle, minidle and maxwait 

        <beans:props>
            <beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect
            </beans:prop>
            <beans:prop key="hibernate.show_sql">true</beans:prop>

            <beans:prop key="hibernate.hbm2ddl.auto">update</beans:prop>

            **<beans:prop key="maxwait">10000</beans:prop>
            <beans:prop key="maxidle">25</beans:prop>
            <beans:prop key="minidle">5</beans:prop>**



        </beans:props>

This message indicates that the process is running out of sockets; that is - too many connections, too fast, between the client and the data-tier server (where MySQL resides).

It happens when connection in pool somehow expired and can't reconnect

https://forum.hibernate.org/viewtopic.php?f=1&t=985002

http://forums.mysql.com/read.php?39,139821,154688

Try to change pool settings (timeouts, idle_test_period, testConnectionOnCheckin etc.) 

<prop key="hibernate.c3p0.min_size">5</prop>
<prop key="hibernate.c3p0.max_size">100</prop>
<prop key="hibernate.c3p0.timeout">300</prop>
<prop key="hibernate.c3p0.max_statements">50</prop>
<prop key="hibernate.c3p0.idle_test_period">60</prop>
<prop key="hibernate.c3p0.acquire_increment">2</prop>

Or if you have DataSource like this try to play with the settings

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
      destroy-method="close">

    <property name="minPoolSize" value="5"/>
    <property name="maxPoolSize" value="5"/>
    <property name="maxStatements" value="500"/>
    <property name="loginTimeout" value="300"/>
    <property name="initialPoolSize" value="5"></property>
    <property name="checkoutTimeout" value="1000"/>
    <property name="automaticTestTable" value="C3P0_TEST_TABLE"></property>
    <property name="testConnectionOnCheckin" value="true"></property>
    <property name="idleConnectionTestPeriod" value="60"></property>

</bean>
