>             Project: Ignite
>          Issue Type: Bug
>    Affects Versions: 1.6
>            Reporter: Ksenia Rybakova

> Configuration:
> - 3 drivers at 1 host, 30 servers at 3 hosts;
> - all operations are enabled except SCAN_QUERY, SQL_QUERY and CONTINUOUS_QUERY
> - for other settings see attached benchmark-cache-load.properties file
> Steps to reproduce:
> 1) Run load test:
>  ./bin/benchmark-run-all.sh config/benchmark-cache-load.properties
> 2) Check all server log files. 
> Note: In my case I noticed that all these exceptions happened only at 20th 
> server (1st server node at the 3rd host), so see 
> 20160511-ignite-1.6.0-SNAPSHOT-37c03c22-pr670-c3-s40/logs/servers/10.20.0.223/logs-20160511-040658/logs_servers/040710_id20_10.20.0.223.log

> Expected:
> No exceptions.
> Actual:
> "java.lang.IllegalStateException: Row conflict should never happen, unique 
> indexes are not supported" exceptions accur while running load test 
> benchmark. 
> java.lang.IllegalStateException: Row conflict should never happen, unique 
> indexes are not supported.
