two environments, production and disaster recovery, both with two websites. all four have the same license key in a file appSettings.config:


<appSettings>
...
<add key="EO.Web.License" value=".............."/>
...
</appSettings>


referenced from web.config file:

<appSettings configSource="appSettings.config"/>



all four sites running fine then suddenly started getting the license warning from one prod webserver. failed over to disaster recovery, both sites fine then 4 days later start getting the license warning on one of the dr webservers.


restarting iis sometimes 'fixes' the problem but not always


dont think this is necessarliy an eo issue as we also have probelms with log4net on the same machines at the same time. log4net is failing to log errors but not reporting any exceptions (that we can find).

so, this looks like both the eo and log4net components are sometimes unable to access the config files.
