[j-nsp] 2x EX4200 Virtual Chassis Layer2/3 - Which JunOS Version ?

[Wojciech Owczarek]

Thought you might find this useful as well:

I know that there is a memory leak issue on JunOS 10.0 for EX4200 affecting VC stacks in particular where the stack members fall over from memory exhaustion when the uptime reaches around 360 days. Can't remember which release fixes it though.

Wojciech

Be sure to have your ISP send you JUST the default. ;)
