Known problems and limitations in Serviceguard • QXCR1001316351: In a very rare condition cmcld will dump core during shutdown of a node. Since package failover takes place and application does not stop there is no visible impact to the end user. • QXCR1001335928: In a very rare condition cmcld may dump core when multiple commands are run in parallel. Multiple Serviceguard command executing in parallel is an unlikely scenario for a customer.
