We are currently investigating problems regarding a failing AsyncIndexUpdate. The first error message starts like this:

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.
