The issue reappeared in Windows 2012, but fine in Windows 2008 R2. Could
someone confirm it? It seemed to be related to clearSnapshot.
Running 2.0.9

> Key: CASSANDRA-6283
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6283
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Windows 7 (32) / Java 1.7.0.45
> Reporter: Andreas Schnitzerling
> Assignee: Joshua McKenzie
> Labels: Windows, compaction

> Files cannot be deleted, patch CASSANDRA-5383 (Win7 deleting problem) doesn't
> help on Win-7 on Cassandra 2.0.2. Even 2.1 Snapshot is not running. The cause
> is: Opened file handles seem to be lost and not closed properly. Win 7
> blames, that another process is still using the file (but its obviously
> cassandra). Only restart of the server makes the files deleted. But after
> heavy using (changes) of tables, there are about 24K files in the data folder
> (instead of 35 after every restart) and Cassandra crashes. I experiminted and
> I found out, that a finalizer fixes the problem. So after GC the files will
> be deleted (not optimal, but working fine). It runs now 2 days continously
> without problem. Possible fix/test:
> I wrote the following finalizer at the end of class
> org.apache.cassandra.io.util.RandomAccessReader:
> {code:title=RandomAccessReader.java|borderStyle=solid}
> @Override
> protected void finalize() throws Throwable {
> deallocate();
> super.finalize();
> }
> {code}
> Can somebody test / develop / patch it? Thx.
