------------------------------------------
Summary: Exception in CompactionExecutor leading to tmplink files not being removed

URL: https://issues.apache.org/jira/browse/CASSANDRA-13545
Project: Cassandra
Issue Type: Bug
Components: Compaction
Reporter: Dmitry Erokhin
We are facing an issue where compactions fail on a few nodes with the following message
{code}
ERROR [CompactionExecutor:1248] 2017-05-22 15:32:55,390 CassandraDaemon.java:185 - Exception in thread Thread[CompactionExecutor:1248,1,main]

Also, the number of tmplink files in /var/lib/cassandra/data/<keyspace name>blocks/tmplink* is growing constantly until node runs out of space. Restarting cassandra removes all tmplink files, but the issue still continues.
We are using Cassandra 2.2.5 on Debian 8 with Oracle Java 8
