Memcached，内存池已满

可以通过增加缓存池的大小或调整数据存储的时间来解决此问题。

示例代码：

// 创建一个 Memcached 配置实例 $memcachedConfig = array( 'servers' => array( array('localhost', 11211) ),

'options' => array(
    Memcached::OPT_DISTRIBUTION => Memcached::DISTRIBUTION_CONSISTENT,
    Memcached::OPT_LIBKETAMA_COMPATIBLE => true,
    Memcached::OPT_NO_BLOCK => true,
    Memcached::OPT_TCP_NODELAY => true,
    Memcached::OPT_CONNECT_TIMEOUT => 1000,
    Memcached::OPT_RETRY_TIMEOUT => 30,
    Memcached::OPT_SEND_TIMEOUT => 750 * 1000,
    Memcached::OPT_RECV_TIMEOUT => 750 * 1000,
    Memcached::OPT_POLL_TIMEOUT => 1000,
    Memcached::OPT_SERVER_FAILURE_LIMIT => 2,
    Memcached::OPT_RETRY_TIMEOUT => 2,
    Memcached::OPT_COMPRESSION => true
)

);

// 设置缓存池的大小 $memcached = new Memcached(); $memcached->setOption(Memcached::OPT_NO_BLOCK, true); $memcached->setOption(Memcached::OPT_TCP_NODELAY, true); $memcached->setOption(Memcached::OPT_CONNECT_TIMEOUT, 1000); $memcached->setOption(Memcached::OPT_RETRY_TIMEOUT, 1); $memcached->setOption(Memcached::OPT_SEND_TIMEOUT, 750 * 1000); $memcached->setOption(Memcached::OPT_RECV_TIMEOUT, 750 * 1000); $memcached->setOption(Memcached::OPT_POLL_TIMEOUT, 1000); $memcached->setOption(Memcached::OPT_COMPRESSION, true); $memcached->addServer('localhost', 11211); $memcached->setOption(Memcached::OPT_HASH, Memcached::HASH_MD5);

// 查询数据 $value = $memcached->get('my_key');

// 设置缓存 $memcached->set('my_key', $my_data, 86400); // 24小时过期

// 删除缓存 $memcached->delete('my_key');
