> Difficult to write a test. Can't reproduce on my computers :(. Flackly
> appears on a server (4 core x 4 cpu) with 100G of the test cache data and
> million+ pages to checkpoint during defragmentation. More often, this occurs
> with pageSize 1024 (to produce more pages).
> Regarding my diagnostic build, I suppose that a fresh, empty page is caught
> in defragmentation. Here is a page dump with test-expented PAGE_OVERHEAD
> (=64) and same error a bit before copyPageForCheckpoint():
> {code:java}
> org.apache.ignite.IgniteException: Wrong page type in checkpointWritePage1.
> Page: Data region = 'defragPartitionsDataRegion'.
