Recommendation

Avoid running commands with long outputs. It is safe to periodically restart the smand with the command test platform software process exit shell-manager RP active stateless. If this doesn't provide temporary relief, you may need to reload the device. However, because the underlying condition is still present, the only permanent solution is to upgrade software to a fixed release.
