Re: [infinispan-dev] Write Skew issue (versioning)

Hi Pedro and thanks for reporting this. Do you have versioning enabled? Otherwise the writeSkewCheck won't be performed at commit time. If you do have versioning enabled, may I suggest to take this on the user forums[1] - this way it would be easier for other users that have the same problem to find it.

In 5.0.1.Final, it works as expected. However, on 5.1.0.CR4 > I have a lot of repeated values.
