[Mono-list] Single File Build Failed Exception in ASP.NET MVC Website

[JamesWright]

I've been running my ASP.NET MVC website (built with VS2010) with Mono hosted
Amazon Linux for nearly two years and occasionally (once a month) get the
error detailed below. Once a page breaks in this way it remains broken until
I restart apache. Previously this error occurred on a relatively obscure
page so it's not been a major problem, however it's now reared its ugly head
on a high traffic page and filled the logs with exceptions. I'd like to get
to the bottom of this because apart from this one issue the platform has
been rock solid stable.

The problem appears to occur after an Apache restart, the page is hit, then
the MVC View Engine tries to compile the ASPX page for the first time. 

Potential workarounds / solutions;

1) Upgrade to Mono 3.0 (may or may not fix it)?

2) Precompile the web pages (so Mono won't attempt to build the page at
all)?

3) Track down and fix the issue in Mono itself?


Server:     Amazon Linux (RHEL/CENTOS based distro) 64 bit
Mono:       2.10.8 compiled form source + mod_mono running under Apache
Framework:  ASP.NET MVC 2

Any help or insights into this problem would be appreciated!
