memcached经常频繁死掉 #264

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.memcached进程每隔一段时间都无缘无故死掉
2.memcached的内存使用达到所设置的上限之后很容易出现timeout
3.timeout一段时间之后memcached进程就会挂掉

What is the expected output? What do you see instead?
