FileCacheStore does not seem to close open files on Windows ----------------------------------------------------------- Key: ISPN-1936 URL: https://issues.jboss.org/browse/ISPN-1936 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 5.1.2.FINAL Environment: Windows 7 Reporter: Matthew Farwell Assignee: Manik Surtani Priority: Critical Fix For: 5.1.3.FINAL Attachments: config.xml, console-1000.out, console-10000.out, Test.java Using the following java (see Test.java): public static void main(String[] args) throws Exception { DefaultCacheManager manager = new DefaultCacheManager("config/config.xml"); Cache<String, String> cache = manager.getCache("evictionCache"); for (int i = 0; i < 10000; i++) { cache.put("key" + i, "value" + i); } cache.stop(); manager.stop(); } with the following config (see config.xml): <infinispan> <namedCache name="evictionCache"> <loaders passivation="false" shared="false" preload="true"> <loader class="org.infinispan.loaders.file.FileCacheStore" fetchPersistentState="true" ignoreModifications="false" purgeOnStartup="false"> <properties> <property name="location" value="d:\code\infinispan\store" /> </properties> </loader> </loaders> <eviction maxEntries="5000" strategy="LRU" /> <expiration lifespan="60000" maxIdle="10000" wakeUpInterval="500" /> </namedCache> </infinispan> running under Windows 7, there are two problems: 1) There are lots INFO: Unable to remove empty file d:\code\infinispan\store\evictionCache\-1134715904 - will try again later. I'm running under windows, so this may have something to do with it, but the process which is holding on to the file handles is the jvm. Is it possible that something somewhere is holding the files open somewhere? Looking at the code in FileCacheStore, there doesn't seem to be anything obvious. 2) This may be related to the above, but the process eventually falls over with java.nio.channels.ClosedByInterruptException (with iterations = 1000) see console-1000.txt or a java.io.EOFException: The stream ended unexpectedly. for iterations = 10000 (see console-10000.txt).
