Tomcat Blocks and Not Responding

У меня есть сервер tomcat, и я запускаю Performance Test с junitperf против него.Tomcat Blocks and Not Responding

Я создаю 20 одновременных запросов каждый раз.

ОК, вот в чем проблема: иногда он возвращается очень быстро, все 20 запросов откликаются в течение 3 секунд; но в других случаях он, кажется, блокируется навсегда и никогда не заканчивается (на самом деле, около 18, 19 из этих запросов будут завершены, а остальные 1 или 2 просто заблокированы навсегда)

Вот как я попытался отладить проблема:

на стороне клиента:

WebConversation webConversation = new WebConversation(); 
System.out.println("Before calling " + url); 
WebResponse response = webConversation.getResponse(request); 
System.err.println("Called " + url);

на стороне сервера, в самой первой строке функции сервлета, у меня есть:

Теперь, когда он блокирует , на стороне клиента я вижу 20 «Перед вызовом» и 18,19 «Вызывается ...». На стороне сервера я также вижу только 18,19 «Ввод сервлетов».

Так что я думаю, что проблема в том, что клиент уже отправил запросы, но сервер Tomcat не отвечает на них, функция Servlet даже не вызывается.

Между тем, когда я проверил журнал, я не нашел ничего о том, почему он заблокирован. Нет информации об ошибке, никакого исключения, ничего.

Может кто-нибудь помочь мне с этим?

Edit # 2:

Вот полный поток свалка:
