Cluster with non-shared JDBC cache store has too much entries after node failure -------------------------------------------------------------------------------- Key: ISPN-2198 URL: https://issues.jboss.org/browse/ISPN-2198 Project: Infinispan Issue Type: Feature Request Components: Loaders and Stores Affects Versions: 5.1.5.FINAL Reporter: Radim Vansa Attachments: cache_entries.csv, logs.zip, sfout.txt In resilience test with 4-node cluster where one node is killed a weird situation appears. Before the node kill have this number of entries: 210602;215820;209400;203038 = 838860 entries After the kill the number of entries changes for a while: 210602;null;209400;203038 250602;null;269400;243038 290602;null;269400;273038 300602;null;289400;293038 300602;null;289400;293038 321218;null;296035;293038 But then it stabilizes on 326899;null;305039;314165 = 946103 entries When the node02 is restarted it complains about duplicit entries: ERROR [org.infinispan.loaders.jdbc.stringbased.JdbcStringBasedCacheStore] (OOB-124,null) ISPN008024: Error while storing string key to database; key: '8Az4Ia2V5NzYzNDI=', buffer size of value: 1050 bytes: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '?8Az4Ia2V5NzYzNDI=' for key 'PRIMARY' Is this a bug or wrong configuration?
