[infinispan-issues] [JBoss JIRA] (ISPN-7089) SingleFileCacheStore; Metadata is sometimes corrupted

[Elias Ross (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-7089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13393260#comment-13393260 ] 

Elias Ross commented on ISPN-7089:
----------------------------------

Code is:

         // sanity check
         if (fe.size < KEY_POS + fe.keyLen + fe.dataLen + fe.metadataLen) {
            throw log.errorReadingFileStore(file.getPath(), filePos);
         }

Perhaps this check does not apply for very large files, especially if the file is > 2GB? It seems to have consistently happened on a number of hosts.
