Making that location writable to everyone is a Bad Thing.

We've seen these errors as well.  Mono wants to write them to the home 
directory of the executing user, most likely apache.

What we've ended up doing is to create a ".mono" directory in the apache 
home directory (usually /var/www on CentOS) and make that writable to 
user/group apache:

mkdir -p ~apache/.mono
chown -R apache:apache ~apache/.mono
chmod u+rw ~apache/.mono

Hope this helps,
