I was hoping someone might have seen the same recurring errors our client's site is experiencing. I initially thought they were being caused by failures in the re-caching of the various important bits of storefront after the regular app pool recycle we have configured, but not all the occurrences tally. There's no evidence I can see that a recycle would have been triggered by IIS and no log of the ASPDNSF restart in the syslog table, so I am at a bit of a loss. In all cases, recycling the app pool clears the error.
The errors are as follows:
AppConfig Table Is NULL!! First, Please re-start your web site, and re-try. If that does not resolve it, please contact support
ISAPI C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'.
Struggling to find any information on this one
