哪个安装文件，我最近优化过代码，给你个版本在验证下。

是不是这个：

rufengsuixing commented 5 years ago

正在测试，暂时没再出现

rufengsuixing commented 5 years ago

最新版还是出现了 2019-02-12 06:47:47,584][ERROR][ smartdns.c:319 ] process exit with signal 11, code = 1, errno = 0, pid = 12, self = 16820, pc = 0x41585c, addr = 0xc, build(Feb 11 2019 11:33:15) Feb 12 06:47:53 【smartdns】: 重新启动0

到现在没有再出现异常退出

pymumu commented 5 years ago

在试一下这个版本，规避了一下异常。应该不会crash了，但关注一下功能有没有一异常

rufengsuixing commented 5 years ago

client is invalid 影响了加入ipset的操作，因为我这里ttl是300，就会导致300s加不入list

pymumu commented 5 years ago

是开启了prefetch功能了吧

rufengsuixing commented 5 years ago

是的开启了

pymumu commented 5 years ago

修改了一下，prefetch有分支未处理。

另外增加了ipset-timeout yes配置，支持ipset超时 但要注意，创建ipset的时候，需要设置启用timeout功能 如：

ipset add foo hash:ip timeout 0
