## Symptoms

- * Short traffic outage occurs after update of CPUSE Deployment Agent (either in Gaia Portal, or manually).

* Cluster failover occurs after update of CPUSE Deployment Agent (either in Gaia Portal, or manually).

## Cause

Chain of events:

1. Update of CPUSE Deployment Agent requires the restart of *confd* daemon (which is responsible for Gaia database and Gaia configuration).
2. When *confd* daemon is starting, by design, it restarts any currently running *routed* daemons (by sending a TERM signal). It is done to avoid possible issues in Gaia Clish (e.g., returning invalid results for routing-related commands like "*show route*").
3. Since *routed* daemon is responsible for all the routing in Gaia OS, short traffic outage might occur while *routed* daemon is being restarted.
4. Since *routed* daemon is a Critical Device in Check Point cluster (since R76), cluster fail-over might occur while *routed* daemon is being restarted.
