Joshua McKenzie commented on CASSANDRA-6283:
--------------------------------------------
I've created CASSANDRA-6832 regarding the leak on repair -par to get a patch
into the code-base for it without being blocked on this.
Andreas - those logs have 100+megs of the same stack traces repeatedly which
unfortunately doesn't help me much. I was hoping to see some information about
process start-up in there. Do you have a small dataset I could use to attempt
to reproduce the errors you're seeing? Alternatively - if you start up a clean
test cluster on 2.0.5 in your environment do you see those errors?
> Windows 7 data files keept open / can't be deleted after 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.
