你用的是最新版本吗？
我看日志行号和最新版本不一致。你升级一下最新版本看看。

是最新版的

你安装的那个文件？
我编译一个调试版本给你，收集点定位信息

from smartdns.

smartdns.1.2018.12.02-1745.mips_24kc.ipk

from smartdns.

smartdns.1.2018.12.10-2316.mips_24kc.zip
编译了一个debug版本，进程挂掉的话，会在/tmp目录下生成一个core文件。

到时把那个core文件发一下。

这回退出原因未知，没发现有core文件

from smartdns.

smart版本

from smartdns.

你的使用场景是什么样的，还有dns服务器的配置

from smartdns.

晚上挂迅雷下东西，dns的话用的数量比较多，查询方式包括tls，TCP，UDP三种都有。
刚才又发生了退出，

同样没有core文件，同时也在使用迅雷下东西
xxxxx.xx是代理服务器SSR的网址，这个和使用ssr有关吗

from smartdns.

有作为TCP服务器吗？TCP有个地方可能导致异常退出。

有用TCP访问smartdns吗？
还有你用的安装包时哪个？我给你个版本看看。

from smartdns.

smartdns.1.2018.12.10-2316.mips_24kc.ipk
我之前是将SSR的解析dns设为192.168.1.1

from smartdns.

smartdns_build.zip

可以试一下这个，这个还没正式发布。
增加了ipset和ip黑名单。

from smartdns.

(^o^)/，我先试试

这次没有使用迅雷，也没有使用smartdns作为SSR的上游服务器

from smartdns.

我现在将smartdns设置成53端口，看会不会出现这个现象

from smartdns.

进程收到10信号比较奇怪，感觉是外部因素导致的进程退出
正常情况和监听哪个端口应该没关系。

你之前监听的什么端口？

执行一下dmesg看看有什么信息

from smartdns.

之前是5354端口，但是换了之后到现在还没出现错误。
现在执行dmesg的信息

最后还是崩溃了，只是时间长了很多。

你的网络质量很差啊。是移动的网络吗？

from smartdns.

是移动的校园网

Archive.zip

再看看吧，我这里压力测试没出现，问题定位周期可能比较久。
如果还出现，尝试关闭smartdns的tcp端口，仅用udp提供服务

from smartdns.

现在关闭了tcp服务器，只用tls

from smartdns.

推测问题出现在smartdns作为TCP服务器的时候，和上游配置无关。上面那个安装包修改了一个可能的地方。
所以先不更改配置，用我上面发的那个程序，再配合你之前的配置验证下看看。

不行再将smartdns的TCP服务器关掉。（不是上游TCP配置）

from smartdns.

OK

from smartdns.

再次崩溃，[2018-12-21 09:57:16,784][ERROR][ dns_client.c:619 ] message type error.

from smartdns.

有什么办法可以让他自动重启吗

from smartdns.

你把TCP服务器关掉（非上游服务器），然后再看看。

我这里压力测试两天了，10个客户端并发请求，每秒1000次，没法复现。

mips系统没有办法打印调用栈。最好是你把coredump文件收集一下。
否则我这里现在比较难找到问题原因。

如果你要自动重启，需要自己写脚本监控。

from smartdns.

TCP服务器上次就已经关闭

from smartdns.

压力测试很久（包括模拟网络不通，模拟服务器不通，多个IP有些响应，有些不响应），无法复现。
看代码，没有找到可能的地方。
可能是那个特殊配置导致触发了BUG。

详细描述一下你的使用场景

1. 在什么设备里面运行。
2. 有多少个客户端。
3. 是否局域网使用。

把你的配置信息作为文件发给我。包括
/etc/config/smartdns/
/var/etc/smartdns/

另外，如果可以的话。

收集一下coredump文件。

from smartdns.

coredump文件似乎没有生成，找不到系统的coredump文件

from smartdns.

smartdns_build.zip

你先拿我压力测试过的版本看看。
我在用你的配置复现看看。

另外，你的上游配置太多，对smartdns压力不小，作业也不会特别明显，还可能拖慢响应速度。
并且最大只支持32个上游，多余的配置都无用了。

建议是，优选几个可信，速度好的上游，上游包含TLS，TCP服务器。
个数控制再20个以下。

from smartdns.

嗯嗯

from smartdns.

Release 18应该解决了此问题，请取用验证。

如还有问题，请reopen issuel

from smartdns.

我最新版本用作tcp服务器的时候也出现了很多这样的日志

aarch64 架构下遇到 SIGSEGV 。附件中是 core 文件及 smartdns 二进制

smartdns-core.zip

@pymumu 可以看看具体是什么原因。在日志里我没看到有特别明显有用的日志，在某一时间点突然间就挂掉了。

/usr/sbin/smartdns -v
smartdns 1.2020.09.08-2235

from smartdns.

这个问题一直没有定位到原因，可能和ssl有关系。

from smartdns.

sendto 2001::, id 1, Permission denied
process exit with signal 11
42版本复现
平台：armv7
环境：ImmortalWrt 21.02.6 r20007-6e54cb5d37

发复现的配置，可能的域名，还有对应的log。

我定义的配置为（未定义的配置均为luci默认配置，第二DNS未开启，未配置dnsmasq，luci自定义设置全部注释，以下配置为根据luci中的设置还原）：

server-name smartdns

bind [::]:7162

proxy-server socks5://192.168.0.1:7891 -name Proxy

domain-rules /domain-set:gfw/ -n remote -c none -r fastest-response -d no -no-serve-expired

当时我没开LOG，我是发现内网的dns查询完全瘫痪的时候上去打开的日志
打开日志之后的操作：进luci点重启，起不来，多次尝试重启无果后重启设备，重启设备之后smartdns正常启动
重启的日志是：
sendto 2001::, id 1, Permission denied
process exit with signal 11
process exit with signal 11
process exit with signal 11
process exit with signal 11
process exit with signal 11
...
很遗憾没有其他更多的有用信息了..

from smartdns.

是用的最新代码，还是release 42版本？

还有，发一下完整的log，包括“process exit with signal”

from smartdns.

用的是imm软件源中的版本

root@ImmortalWrt:~# smartdns -v
smartdns 42

当时重启得比较着急，完整的包含时间戳的日志已经没了（忘记保存下来了）
不过日志就是上面那些，点重启之后一直重复报，没有其他信息
process exit with signal 11

from smartdns.

看看能不能找到复现方法把，要不然也不知道异常原因。

这个可能是短时间内，有某个请求出发了同一个BUG。
