We are noticing Ping delay between two VMs in our product.
We have not observed this with “4.18.0-193” kernel, but we are noticing it in “4.18.0-310”, and we are not exactly sure in which kernel version this got introduced/broken.
Response time from VM2 to VM1 used be less than 75ms with
“4.18.0-193” kernel, but we seeing this more than 400ms in “4.18.0-310” kernel, and these VMs are in the same system, but on different sites.
Even without traffic, we see this ping delay issue.
Please let us know if there is any workaround (or) possible solution for this.
Current Alma8, 8.7, has kernel-4.18.0-425.
There were apparently never 310 and not in CentOS Stream 8 either.
There definitely were no 193 in Alma, but RHEL 8 and CentOS Linux 8 had one.
Can you reproduce the issue with current Alma release content?
We started to notice this ping delay with CentOS 8.5 itself (using kernel 4.18.0-348) and we see the same issue in our next releases with AlmaLinux 8.6 (using kernel 4.18.0-372).
However we are not observing this issue when downgraded kernel to 4.18.0-193. Please note that in our earlier releases using 4.18.0-193, this issue was not observed, which is the reason to test with downgraded kernel.
