Mmmmh, I think someone who hasn t read the manual pages has put a
flux->writeComplete() into my engine callback 8)
... implying a 2^N callback calls for each data push at the entry of the
engine chain (of N engines).
So I swear not to forget to forget the writeComplete() in the engines ;)
pfApologies,
Marc.
