Hello every body

I have a problem. I work with GNS3 for my CCIE. My lab is essentially composed of 3725 and I use the IOS c3725-mz.124-adventerprisek9-15.T6.bin.

I have an I7 with a 6 GB of RAM and I work with Ubuntu.

All routers boot fine, and I can connect to the console, but after some times I lose connection to my console for some routers (the consoles are opened but I can't access them)

Please someone can help me ?
all support is welcome

please find below gns3 file (from IPEXPERT)

I would suggest uncompressing the images:



Then:
1. edit your config file to say c3725-advipservicesk9.124-15.T6.image rather than c3725-advipservicesk9.124-15.T6.bin
2. Add the image c3725-advipservicesk9.124-15.T6.image in Edit->IOS images and hypervisors
