Check_MK discovery is flapping and Timed out

[a3093 (Gonzalo)]

I have the same problem and it is repeated a lot in the forum.

Here’s a possible solution that I haven’t tried yet:

CMK 2.1: service discovery fails for slow devices

Thanks for pointing out the solution, we also have the same problem @bitwiz described after an upgrade to 2.1.x We had no problems with version 2.1.0. Only today after I updated to 2.1.0p16 there are these problems with Huawei switches.
