Infinispan rejects to read cache file bigger than 2147483647 (Integer.MAX_VALUE) -------------------------------------------------------------------------------- Key: ISPN-8691 URL: https://issues.jboss.org/browse/ISPN-8691 Project: Infinispan Issue Type: Enhancement Components: Loaders and Stores Affects Versions: 9.1.1.Final Reporter: Dmitry Katsubo Priority: Minor In my scenario the cache file size created by {{SingleFileStore}} is 3.054.196.342 bytes. When this file is tried to be loaded, it fails with the following exception: {code} Caused by: org.infinispan.persistence.spi.PersistenceException: ISPN000279: Failed to read stored entries from file.

I have tried to configure the persistence storage so that it gets purged on start: {code} <persistence passivation="true"> <file-store path="/var/cache/infinispan" purge="true"> <write-behind thread-pool-size="5" /> </file-store> </persistence> {code} however this does not help as storage is first read and then purged (see also ISPN-7186). It is expected that {{SingleFileStore}} either does not allow to write such big entries to the cache, or handles them correctly.
