[Bug] 太多的 process not found

[WangHaonie]

短短 50 秒内刷出了 17000 多行 process not found，就算是同一个软件发出的请求，有时找得到进程，有时就找不到，实在是找不到进程就算了，只需报一行就OK，不然整个日志都是 process not found，影响后续分析，希望可以修复一下。

刚试了最新的 alpha-cd44901，问题依旧

[xishang0128]

@WangHaonie debug log刷屏不算bug

[vj23456]

@WangHaonie 你别写process规则就没了

[H1JK]

This is indeed a problem. In the current implementation, the PROCESS-NAME rule will trigger the process name lookup and cache the result, but if the process name lookup failed (and nothing got cached), the process name will be looked up again every time matching the PROCESS-NAME rules and then the error will be reported repeatedly.

May we only need one such error message per connection, or never do match once failed?

最容易出现的环境其实是路由器或者非本机代理，其实可以对非本机 IP 进行过滤

试试在相同配置下，还会重复查询进程么

[WangHaonie]

253c1f4 数量确实比之前少了不少 @Skyxim

之前：

c57f17d 也OK

[H1JK]

The repeated error in the previous version is mainly because your configuration uses PROCESS-NAME too frequently. Now we no longer retry failed process lookup.

However, it's still not clear why your process lookup was failed (and even not completely failed).
