pika莫名其妙的OOM #2947
Comments
确认是否使用tcmalloc,需要做定时清理工作, 确认一下是否有 Table Cache 这个配置项 |
Confirm whether to use tcmalloc, you need to do regular cleanup work, and confirm whether there is a Table Cache configuration item |
可以看下是不是同一个问题:#2537 (comment) |
OOM的时候 tablereader内存使用并不高,才8G左右,而且当时QPS还不到100,连接数也100左右。从节点比主节点早20分钟OOM,从节点没有连接使用。 我更想搞明白:除了tablereader这8个多G 内存外,还会有什么占用内存会导致进程内存到15G多而OOM

版本:3.3.6
服务器配置: 8C16G1TSSD
监控中内存使用并不是很高,实例数据也才100G左右。
客户端也100个左右
服务器内存使用率接近100%,把pika oom kill了
监控看内存使用率并不高,但是进程的内存一直在增加,最后导致了OOM。
没找到什么头绪
