Aaron Morton commented on CASSANDRA-2290:
-----------------------------------------
Not sure if this helps. I found a place where AES was hanging while testing
failure during streaming transfer for CASSANDRA-2088. I broke the
FileStresmTask to only send one range and close the sending channel.
The IncomingStreamReader.readFile() got stuck in an infinite loop because it
does not check the return from FileChannel.transferFrom(). It was returning 0
bytes read. Also the FileStreamTask does not check the bytes sent by
transferTo()
While stuck in the loop the socket it was reading from was (127.0.0.1 was in
the loop, .0.2 was sending)
java 25371 aaron 73u IPv4 0xffffff8010742ff8 0t0 TCP
127.0.0.1:7000->127.0.0.2:52759 (CLOSE_WAIT)
When I was debugging the socketChannel was still reporting it was open.

> Key: CASSANDRA-2290
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2290
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.6
> Reporter: Sylvain Lebresne
> Assignee: Sylvain Lebresne
> Priority: Minor
> Fix For: 0.7.4
>
> Attachments: 0001-Don-t-start-repair-if-a-neighbor-is-dead.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Repair don't cope well with dead/dying neighbors. There is 2 problems:
> # Repair don't check if a node is dead before sending a TreeRequest; this
> is easily fixable.
> # If a neighbor dies mid-repair, the repair will also hang forever.
> The second point is not easy to deal with. The best approach is probably
> CASSANDRA-1740 however. That is, if we add a way to query the state of a
> repair, and that this query correctly check all neighbors and also add a way
> to cancel a repair, this would probably be enough.
