Sadly we can't do it yet, the improvements colliding with our usage of creating the index with mappings. **But: My initial problem is solved.** **Just for information (and i cant show it), since we use dynamic\_templates there was a real big mapping at the end (didnt expect that), the mapping got a size of 194MB at the crash, now its back to 10KB, since we changed some implementation detail.** Since this will show only on the indexing phase, not with the index creation, we couldnt see it before. For real we only saw it because i stopped the master and the errors with "mapping not found" were in there then. If i didnt stop it, i would still searching for a solution. So @jprante, the reason why we could create such heavy lot is, that we really used massive dynamic\_templates, and the cluster couldnt keep up. _Thanks again @all for all you suggestions, improvements and comments._ ---
