I have multiple threads each updating different documents. No thread is updating the same document. The update is like this:  
ctx.\_source.abc.list\_a = params.a\_list;  
ctx.\_source.abc.list\_b = params.b\_list;  
ctx.\_source.abc.list\_c = params.c\_list;

list\_a, list\_b, list\_c are nested. Some of the threads succeed in updating the documents and some don't.  
I am seeing the following error:

version conflict, current version [55] is different than the one provided [54]
