At that point my lb is not able to ping the 10.42.244.70 (nginx) anymore.
And now i’m going to wait some minutes (5-10min) and my lb is able to ping 10.42.244.70 again…
If i run the test again, it is failing after some seconds again…
Could you please repeat that test in your Infrastructure? Maybe i got a bug in my infrastructure… Or it’s in the multihost-networking implementation… i hope it’s the first one
This sounds like you’re probably running out of ephemeral ports in the balancer container because it’s a large number of short requests coming from a single source…
Or apparently there’s a similar sort of issue with the IPSec routing table for the overlay network, which is probably more likely since you said a single host works fine. There’s a fix for that in the next release.
Could you reconstruct my problem? Would be really nice, if that would be fixed. If you want to go to production in high-load applications it’s a must i guess…
There is a fix with the ipsec in v0.42.0. Could you test with that version to see if it fixes your issue. It fixed another person’s issues that were similar.
