Sanne Grinovero updated ISPN-1362:
----------------------------------
Summary: Lower the amount of files a FileCacheStore will create (was: FileCacheStore should limit the number of files kept open at the same time)
Description:
It seems that after ISPN-1300 we allow the FileCacheStore to use _only_ approximately 4 millions of files, this is still too much as the original issue description reports:
When trying to initalize my index for Hibernate search with persistance I get the following exception after several hours of indexing:
