[Mono-aspnet-list] Problem With Mono + Apache2 with Mod-Mono

[Marcos Junior]

> I'm trying to configure my MVC ASP-NET 4 application with mod_mono and
> apache2.
>
> I can successfully run the application when the machine comes from a
> reboot (or restarting services and clearing temp files). All works fine.
>
> The problem is when I try to recompile the binary and replace it on the
> production server's bin folder, apache stops responding. Browser seats
> waiting for timeout. The mono-ctrl handler also stops responding. I cannot
> find any useful logs.
>
> Thanks for helping.
