访问Ignite缓存进行查询时，出现“ 缓存已关闭”异常。我正在做的很简单，
asm{}初始化此代码后，在我代码的其他位置调用CacheConfiguration cfg = new CacheConfiguration();
cacheConfiguration.setCacheMode(CacheMode.REPLICATED);
cacheConfiguration.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT); cacheConfiguration.setWriteSynchronizationMode(CacheWriteSynchronizationMode.PRIMARY_SYNC);
IgniteCache cache = ignite.getOrCreateCache(cfg);
；但这引发了异常。
缓存变量是某个类的对象的成员。为什么直到手动关闭缓存后才能保持打开状态。
我什么都没关上

通常会发生这种情况，因为您没有在代码中的任何地方调用FFI::NotFoundError: Function 'getdtablesize' not found in [libc.so]

或。.close()时，客户端断开连接，服务器关闭或客户端重新加入新ID。
