Unable to clear cache. Failed on region entityCacheRegion. Last key null null

[former_member834206]

We are migrating Hybris version from 2011 to 2205 with sapmachine1.17 in our project, when doing update system after "FINISHED. The updating took: 0d 00h:13m:47s:583ms" message getting the error as "Unable to clear cache. Failed on region entityCacheRegion. Last key null null" but the build successfully completed. The same question raised in SAP portal on Dec 22, 2014 in the below link but there is no proper solution to fix the issue. We are not facing this kind of err with Hybris 2011, JDK 11 version in our project. If anyone have answer kindly help us to fix the issue.
