软件测试－硒：由于页面崩溃而删除错误会话的解决方案：[https://blog.csdn.net/troubleshooter/article/details/106472186?utm\_medium=distribute.pc\_relevant.none-task-blog-OPENSEARCH-1.channel\_param&depth\_1-utm\_source=distribute.pc\_relevant.none-task-blog-OPENSEARCH-1.channel\_param][https_blog.csdn.net_troubleshooter_article_details_106472186_utm_medium_distribute.pc_relevant.none-task-blog-OPENSEARCH-1.channel_param_depth_1-utm_source_distribute.pc_relevant.none-task-blog-OPENSEARCH-1.channel_param]

docker在运行时没有设置--shm-size参数，Size of /dev/shm, default value is 64MB；

所以在运行时加上：--shm-size=2g

**docker  配置shm-size大小必须是  宿主机实际内存的一半【比如你的内存我2G，则shm配置为1G】太大会导致内存不足崩溃，太小会导致Selenium程序崩溃！**

### **解决方案：** ###

在docker容器输入命令：

df -Th  # 查看shm的尺寸大小

docker run -it --shm-size=1g 镜像名  # 容量设置大点，这里设置2个G容量
