Force10 s25 switch has a memory leak that I can't solve
I have two buildings in my school district that are linked by 2 Force10
S25 24-port switches over a 10 Gbps dark fiber connection. One switch is
in building "L" and the other is in building "S". Building L also hosts
the internet connection for the district. The switch in Building L is on
the subnet 10.2.0.0 /16. Building S is on the subnet 10.4.0.0 /16. The
switches strictly serve the purpose of layer 3 routing between buildings
and the switch in Building L points at the district's default gateway.
They have very simple configurations with static routes for even more
simplicity. Communication between buildings is fine, but the switch in
Building L runs out of memory every 3 hours or so and needs to be
rebooted. This is obviously detrimental to the school day and general
productivity. When I issue the command show process memory, the process
tFib4 gradually climbs in its memory usage and seems to be the cause of
the problem. The building "S" switch never fails or has this problem. I
have listed the configurations of each below. Any assistance is greatly
appreciated, as I NEED to get this fixed asap.

Building "L" is one firmware version higher because it was supposed to fix
the leak and an internal telnet issue but didn't, so I have not upgraded
the building "S" firmware and will be downgrading the building "L"
firmware.
