Прерывание Исключение при операции ввода SSM Xmemcached

Question

У нас есть выделенный сервер как memcached. Он имеет следующую конфигурацию:

STAT curr_connections 242 
STAT total_connections 684 
STAT chunk_size 48 
STAT num_threads 64 
STAT num_threads_per_udp 64 

Но мы видим исключение InterruptedException для кэша во время установки объекта. ниже являются журналы

Ниже приводится Memcached версии

<dependency> 
    <groupId>com.googlecode.xmemcached</groupId> 
    <artifactId>xmemcached</artifactId> 
    <version>2.0.0</version> 
</dependency> 
<dependency> 
    <groupId>com.google.code.simple-spring-memcached</groupId> 
    <artifactId>xmemcached-provider</artifactId>

<dependency> 
<groupId>com.google.code.simple-spring-memcached</groupId> 
<artifactId>spring-cache</artifactId> 
    <version>3.1.0</version> 
</dependency> 

Я не уверен, что может быть причиной для этого исключения. У нас настроено несколько кэшей, но это исключение встречается только для APP_CACHE_1. Истечение APP_CACHE_1 является 7200.

Answer 1

Попробуйте новую версию xmemcached: 2.2.0, в старой версии была аналогичная ошибка: https://github.com/killme2008/xmemcached/issues/30

Я не проверял, если он совместим с SSM 3.6.0, но стоит попробовать.

Используйте новейшую версию xmemcached-провайдера и яровой кэша: 3.6.1
