> Currently tests 4 are failed in  PDS 2 suite with timeout:
>       IgnitePdsTestSuite2: 
> IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailAfterStart (fail rate 
> 100,0%) 
>       IgnitePdsTestSuite2: 
> IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailWhileStart (fail rate 
> 100,0%) 
>       IgnitePdsTestSuite2: 
> IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailAfterStart (fail rate 
> 100,0%) 
>       IgnitePdsTestSuite2: 
> IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailWhileStart (fail rate 
> 100,0%) 
> Tests were introduced in ticket [IGNITE-7809]. 
> Tests try to emulate failure using exceptions in file IO, but MMap-ed modes 
> does not allow currently to be tested with current tests approach.
> It is suggested to create new testing opportunities for MMap modes.
