After this error happens, every new request to this site will be error. After I restart www, website run normally and a few days later, the error still be found!

I check the function where error happens, I think no error will never appear because it's a very simple statement like that:

try
{
ICriteria crt = _session.CreateCriteria(typeof(CompanyNotify));
return crt.List();
}
catch (Exception ex)
{
logger.Error(ex);
return null;
}

And here is other error found, you can have more detail of what was happen!
