Good point. Still open whether that misformat shall match or not; if
there's just a delimiter missing between '51000' and 'failed' it might
be intentional to extract that line, but then (e.g. if you post process
the output) it might be necessary to strip the string part from the two
glued data fileds. As mentioned in another thread, if the example data
leaves room for many possibilities I'd propose solutions and wait for
any necessary clarification.
