Hello,

Had some issues with a lot of routerboards causing internet service disruption/massive packet loss.
Randomly, the router would not be accessible for 10-30 seconds. No interface flopping logged.
Even weirder, a subnet behind the router will also lose connectivity when this happens.
A netwatch on the router pinging the ISP gateway every second logs problems at the exact time I am unable to access the location remotely.
I have tried several RB1100AHx4 The Dude and finally moved to CHR on a Supermicro server with Intel Xeon, ECC RAM and Intel 10Gb/s nics, inside a VM.
At first, I thought my ISP has issues, seeing so many Mikrotik routers and even CHR behaved the same.
For a time I just decided to not pay attention to this problem, until I decided to disable The Dude.
Lo and behold, the packet loss and service disruptions stopped.
Kept the Dude disabled for one week=no problems at all.
Enabled the Dude again for one week=several issues a day for the whole week.
Disabled the Dude again=no problems at all.
Now it seems very clear to me that the Dude is the cause of all this issues I am having, but at the same time, very few people are reporting this issue. Only one other user to be precise.
I have tried to limit the number of monitored devices, increased the pooling time, monitor only icmp without any other services, all without success.
The Dude database size is 8 Mb so very small.

我在想,如果这是一个家伙的问题,更多topics would show up on a search, but then again, I cannot see any other possibility besides maybe the ISP seeing a lot of icmp at once, considering it a threat and disabling the connection temporary (which they do not admit to)

Anyone else is having massive packet loss while using the Dude?

did you look at the resource use on that device ?

顺便说一句,我从来没有运行2 1日完全的不同的功能device if that device is critical for production ...
a router is critical, a monitor should run on a different device .
