I get this error on one of my branch waes, cant find doc on error, has anyone seen orror or know resolution? Minor: Entering overload state due to Max connections. Total number of entries for this reason: 449.

Is there any other way to achieve failover and/or load balancing on 2 612 aplliances other than inline network adapter cards or pbr(failover)
