Xmemcached异常超时：Timed out waiting for operation

Question

Hi:

   XMemcached版本：1.4.3

   使用spring管理，创建连接时使用MemcachedClientBuilder。

   查询时：client.get(searchPkgNameList, 5);

   其中searchPkgNameList会很大，一次大概有300个key。

   异常信息：

-- Timed out waiting for operation
java.util.concurrent.TimeoutException: Timed out waiting for operation
	at net.rubyeye.xmemcached.XMemcachedClient.getMulti0(XMemcachedClient.java:1245)
	at net.rubyeye.xmemcached.XMemcachedClient.get(XMemcachedClient.java:1119)
	at net.rubyeye.xmemcached.XMemcachedClient.get(XMemcachedClient.java:1157)
	at com.*.appserver.service.AppSearchService.searchAppType(AppSearchService.java:46)
	at com.*.appserver.controller.AppController.searchAppType(AppController.java:84)

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
	at java.lang.reflect.Method.invoke(Method.java:606)

我调整了超时时间，但还是异常。难道是我的一次查的key太多？

另外：warn：

 [net.rubyeye.xmemcached.XMemcachedClient] - You are using connection pool for xmemcached client,it's not recommended unless you have test it that it could increase performance in your app.

是否是不应该使用MemcachedClientBuilder来创建连接？还请帮助。多谢

多谢，是使用Builder来创建client，目前已经来回调整了配置，继续观察情况。
