Cell Data Caching Block Size Properties issue on 14.1.1.6

Hello,

We are experiencing weird behavior when using the particular feature on RPAS 14.1.1.6 through Fusion Client. While in a workbook, very often user sessions freeze without any errors or log messages. 

We used several column and row numbers, always with the same result. The latest settings are the following:

celldatacache.fetch.columns=60

celldatacache.fetch.rows=200

celldatacache.enabled=true

block.celldata.fetch.and.cache.strategy=true

pivottable.fetch.columns=60

pivottable.fetch.rows=200

Finally we tried also without setting the property "block.celldata.fetch.and.cache.strategy" since the default value is true but we got the same behavior.

Are there any known issues with the feature?
