Andreas Schnitzerling commented on CASSANDRA-6283:
--------------------------------------------------
Another relying critical issue: Cassandra can't delete cache files, system.log:
"WARN [CompactionExecutor:53] 2013-11-10 21:41:59,862 AutoSavingCache.java
(line 277) Failed to delete
D:\Programme\cassandra\saved_caches\system-schema_columns-KeyCache-b.db"
That leads to a crash on next start, system.log:
"ERROR [main] 2013-11-12 11:02:43,654 CassandraDaemon.java (line 478) Exception
encountered during startup
java.lang.OutOfMemoryError: Java heap space

> 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
> Priority: Critical
> Labels: newbie, patch, test
> Fix For: 2.0.3, 2.1

> Attachments: screenshot-1.jpg, system.log

> 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:
> @Override
> protected void finalize() throws Throwable {
> deallocate();
> super.finalize();
> }
> Can somebody test / develop / patch it? Thx.
