chủ đề sẽ chặn .. jstack hiển thị như thế này. Tôi chỉ sử dụng nó để thu thập thông tin một số trang web. Điều này xảy ra khi mã trạng thái là 404.
Using Java Apache PoolingClientConnectionManager leaks the Memory,How to solve it? vấn đề của tôi tương tự như vậy.

cách giải quyết?
Vui lòng gắn thẻ này là Java. –
Có phải vấn đề mà chuỗi đang chờ và bạn không muốn nó chờ? –
