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.
