-very simple, much simpler than windows. no house-wife tampons like gns... just install lets say ubuntu-server, put dynamips/dynagen binaries in there and you are done...

Yep, that will happen if your cpu nears its limit... Was happening on my also when I was running it on windows. Scheduling is really bad for these things on it. Ideally I would recommend a souped-up linux server with lots of ram for it. I am running ie scale labs, and I needed two dual-core blades with 4gb worth of memory each. Even on those I can tell a slowdown closer towards where you enable bgp's...

Has anyone experienced instability using Dynamips with constant Spanning
Tree changes e.g. list, lrn, blk, fwd...etc? I believe I'm seeing this
because of the latency associated with running Dynamips on my computer, but
I'm wondering if that's the case or if there's something else inolved
configuration-wise?
here's what I'm seeing on the one device having issues (debug spann
event output):
