Packet drops seen for 20 sec on every 8th day when perf_dhcp tests are run against Kea DHCP service continuously
Hi All, We are running performance tests for kea dhcp using the perf-dhcp provided by kea .
- Setup: Dockerized Kea1.6.2 running in well provisioned hardware.
- Runs details: Running perf-dhcp to generate approx 100 requests/ sec , validating all 4 packet handling DHCP discover request etc. perfdhcp -p 600 -r 100 10.0.0.4 -t 10 this is executed in a loop
- Issue : We observe a 20sec packet drops on requests on every 8th day exactly. The in between days there are no packet losses. There are no restarts of kea-dhcp service. After the packet loss duration, things go back to normal.
- Request: Is there any limits we might be hitting every 8th day of the run? Are there any parameters we should check? It would be very helpful, if we can determine what causes this packet loss.
