[infinispan-issues] [JBoss JIRA] (ISPN-1362) Reduce the number of files a FileCacheStore creates

Reduce the number of files a FileCacheStore creates --------------------------------------------------- Key: ISPN-1362 URL: https://issues.jboss.org/browse/ISPN-1362 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 5.0.0.FINAL, 5.1.0.FINAL, 5.1.1.FINAL Environment: OS: Mac OSX 10.6 IDE: IntelliJ IDEA 10 Java: 10.6.0_26 Hibernate Search: 3.4.0.Final Lucene: 3.1.0 jGroups: 2.12.1.3.Final Reporter: Todd Underwood Assignee: Manik Surtani Labels: persistence Fix For: 5.2.0.ALPHA1, 5.2.0.FINAL 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: [2011-08-29 11:30:53,425] ERROR FileCacheStore.java:317 Hibernate Search: indexwriter-154 ) ISPN000063: Exception while saving bucket
