    Hi,

    You get this exception when 2 threads concurrently try to write to the same location. Does your code do this?

    Hi,

    I'm not sure whether 2 threads concurrently try to write to the same location.

    Can you share the complete stacktrace? It will indicate one thread, which participates in this situation. The other might be much harder to spot.

    If you can recreate this situation, you should enable loglevel trace on org.apache.jackrabbit.oak.jcr.operations.write; this will log every write activity to the repository including the threadname, which does this action. This together with the exception will clearly indicate which threads are causing this situation.

        Did you find a solution for this? We also have the same problem in our translation projects such as:
