关于Java服务长时间运行出现各种bug问题，可能运行几天没问题，但是运行十几天就会出现各种bug

服务使用的是ScheduledThreadPoolExecuto定时任务，有使用到全局变量，数据库连接池使用的是c3p0，我感觉出现问题的原因可能就是这三个里哪个导致的，程序是没问题的，就是运行久了就出现各种问题了，而且很莫明奇妙，比如本来是好好的运行久了日志中的中文从那个时刻起往后全都乱码了。请问这是怎么回事？

定时任务：
ScheduledThreadPoolExecutor bookClickScheduled = new ScheduledThreadPoolExecutor(10);
int checkPHPConfigCycle = Integer.parseInt(Config.getConfig("CheckPHPConfigCycle"));
bookClickScheduled.scheduleWithFixedDelay(new CheckPhpConfigTask(), 0, checkPHPConfigCycle, TimeUnit.MINUTES);

连接池配置:

            <property value="oracle.jdbc.driver.OracleDriver" name="driverClass"/>

            <property value="jdbc:oracle:thin:@10.97.190.14:1521:cmfudv1" name="jdbcUrl"/>

        <property value="" name="user"/>

            <property value="" name="password"/>

    <property value="1" name="minPoolSize"/>

    <property value="2" name="maxPoolSize"/>

    <property value="1" name="initialPoolSize"/>

    <property value="60" name="maxIdleTime"/>

    <property value="1" name="acquireIncrement"/>


    <property value="0" name="maxStatements"/>

    <property value="60" name="idleConnectionTestPeriod"/>

    <property value="30" name="acquireRetryAttempts"/>


    <property value="true" name="breakAfterAcquireFailure"/>

</bean>


    看了一下日志，貌似是服务重启启动了
