> Using validation implemented in IGNITE-7467 we can observe the following 
> situation:
> Let's we have some partition and nodes which owning it N1 (primary) and N2 
> (backup)
> 1) Exchange is started
> 2) N2 finished waiting for partitions release and started to create Single 
> message (with update counters).
> 3) N1 waits for partitions release.
> 4) We have pending cache update N1 -> N2. This update is done after step 2.
> 5) This update increments update counters both on N1 and N2.
> 6) N1 finished waiting for partitions release, while N2 already sent Single 
> message to coordinator with outdated update counter.
> 7) Coordinator sees different partition update counters for N1 and N2. 
> Validation is failed, while data is equal.  
> Solution:
> Every server node participating in PME should wait while all other server 
> nodes will finish their ongoing updates (finish wait for partition release 
> method)
