## Symptoms

- * Users cannot connect to the internet.
* Traffic through a Virtual Switch (VSW) drops intermittently.
* The firewall kernel (FWK) process for the VSW shows continuous high CPU usage.
* In the `perf` output for the relevant FWK process, the `fwmultik_do_seq_on_packet` function appears.

## Cause

The FWK process that handles the Virtual Switch instance is overloaded.

## Solution

A solution was implemented and is included in the below versions, though, it is **disabled** by default and should be enabled.
