- The following error appears on the serial terminal console or DRAC before the system restarts, and a full stack trace appears after it:

- The output of df –h from the STS appliance shows that each partition has at least 20% of its disk space available.
- Dell Hardware diagnostics do not detect any hardware errors or faults.
A mis-configured static route causes STS appliance to send a RST packet through the wrong network interface.
To resolve this issue, please upgrade to Symantec Traffic Shaper 6.1.
If you are not able to upgrade immediately, workaround this issue by locating and correcting the misconfigured static route.
- The STS Appliance is configured in routed mode.
