SocketException Сломанная труба в Solr/tomcat

Question

Я использую Solr 4.3 с tomcat7. Когда число одновременных операций записи и чтения увеличивается, это краш, бросающий эту ошибку SocketException. Я выполняю параллельные транзакции и запросы через несколько клиентов. Любая помощь приветствуется. Вот журнал tomcat (catalina.out) и solr.log

tomcat log(catalina.out):

Answer 1

Это более низкая погрешность. Я нашел это question&answers in stackoverflow, и резюме решений состоит в том, чтобы проверить, действительно ли вы закрываете все сокеты (это было бы косвенно связано с каркасом) и проверить, нет ли у него других исключений (например, требуется больше памяти).

Answer 2

Точка доступа закрыта. Например, вкладка браузера закрыта или переместилась на другую страницу. Нет ничего, что можно или не нужно делать с этим в конце. Вы больше не можете писать ответ, так что перестаньте пытаться.
