GNS3 "Connection to the Host Lost"

[write2irfan]

I am facing issue with GNS3 , in my Topologies , when i try to run Nodes some time some nodes doesnt start. and and i cannot connect to console even.

If i restart Topology , some times it works fine. and also it is changing from Node to Node. LIke if i have 8 Router s, some times R1 is not statring and some times R8 and so on.

I have WIN7 , Any help ?

hi,

check your PC's CPU. maybe pegging it due to simulating too many nodes/routers.

use idlePC values to lower CPU down.

I am using IDLE PC , and i have verified with all nodes.

where as the memory could be an issue, like it first dynamypis file always take 50% of memory.

rest dynamips are between 10 to 18 % as i could see in task manager.
