反复出现重连session #196

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
我使用的是 Xmemcached 1.3.6
配置
cache.memcacheConnectionPoolSize=1
cache.memcacheHost=10.142.4.43:9168 10.142.4.44:9168
cache.memcacheHostWeights1=1
cache.memcacheHostWeights2=1
cache.opTimeout=4500

1.启动后反复出现重连session

2.操作时不时会报Session has been closed异常

3.时不时会报此异常 但代码直接是memcachedClient.get(cacheKey); 
注：此Memcached服务端是某厂商的云平台

不知是何原因？

你的日志不是说了么，服务端不支持GET_ONE命令吧，跟你们云�
��台提供商确认下指令的支持情况呀（服务端遇到不支持的指
令，一般的做法是断开连接）。

此Memcached服务端是某厂商的云平台

不支持multi 
get?确认下这个产品支持和不支持哪些memcached协议。

常规的set add replace get gets cas bget delete Incr Decr append 
prepend都支持

原因可能是他不支持version,stats协议 
而xmemcache的心跳是访问version导致的？那能否在配置中关闭心�
��线程?或者更改心跳命令？

Original comment by akimotos...@gmail.com on 4 Jun 2012 at 6:16

GoogleCodeExporter commented 8 years ago 
可以禁止心跳检测，通过：

memcachedClient.setEnableHeartBeat(false);

也请确认它支持批量get协议，也就是可以一次get多个key。

GoogleCodeExporter commented 8 years ago 
确认他们支持的协议比较少 我们改用了memcache-client-forjava 
感谢killme大侠的support 后续我们再会用xmemcache做测试 
争取找到根本原因

关闭心跳也没有解决？

Killme大侠，生产环境一出现这个日志，所以我在本地进行了��
�下压力测试，发现如果我100个线程请求memcached，不会报如何�
��常日志，但是如果线程数放大到200左右，就会出现以上异常
，和生产环境的日志一样，所以我怀疑是并发的问题，希望��
�能回答，谢谢！

@xieyouping2006@126.com,

你们有使用noreply操作？使用的xmemcached版本是多少。
