HA dedicated management port problem (FG 1240B + FortiOS 5.2.7).

[Jbsd]

Hi, We are having problems with a management port of an HA A-P cluster. Port 40 on both FG`s are connected to a L2 switch in access mode, however the slave firewall mng port randomly stops working but in the switch and the FG it remains as UP. The only way to recover access is jumping from the master and perfrom a reboot.

Does someone has any idea?.

Best regards.
