We have a product that has a C# web app deployed via mono on a linux box commercially shipping for four years. What I found was that with mono 2.10.6 it was fine as long as it was not loaded heavily, but under stress it would have stability issues. The socket layer was rewritten since then however and I've had less issues with 2.10.8/9 but still fails under heavy load. More fixes have gone into mono 3. My sense is that it's getting better but not nearly as battle tested compared to JVM-based network stacks. So if I was coding a large scale web service I'd consider Scala first.

Have you tried using one of the newer versions of Mono (3.2.x)? The SGen GC is much better than the old Boehm-style GC, and SGen itself has improved by leaps and bounds over the past year.

Haven't tested on 3.2.x yet but the GC was never the issue for our stress tests. Bugs in the socket layers were killing us. Better under 2.10.9 but still not completely resolved.
