at that time the application was already running for some hours, this did not happen on startup!
Also the code indicates, that the exception itself is created on creation of the AsyncIndexUpdate
service, so the stacktrace does not give any insight under which condition the exception occurred
at all. This should be changed in a way, that the stacktrace contains relevant information
about the root cause of the exception.
