When a blade fails, any non-mirrored connections on that blade are lost. The loss of these connections are not correctly accounted for when determining LSN client connection count limits. This may cause some clients to reach their connection count limit prematurely.
Client connection count limits reached prematurely.
Blade failure on a chassis based system. This condition is most likely to occur when default DAG is configured on LSN VLANs.
In order to make the client connection counter accurate again an effected client must not have any active connections or make any new connections for a time greater than any connections configured timeout. (default 300 seconds). After the client connection counter entry times out, the client connection counter will accurately reflect the number of client connections.
