SSH connection reset

[#1]

Hello!! I have 2 FGT1000A in HA and when I' m connected from my Pc in my internal network to a server via SSH in other interface (DMZ) , the connection is reset after some minutes (between 30 and 90 min.). This don' t happens always, but it' s very frecuently. Before migrate my network to Fortigate, (previously I had other firewalls not Fortinet) with the same machines, It worked fine. Some idea? Where I can debug this? thanks. Carlos

Adjust your session-ttl time for SSH standard protocol; I.e: for 4 hs,

 config system session-ttl
    config port   
         edit 22
              set timeout 14400
         next
    end
 end
 

I hope it be useful,
