Getting java.net.SocketException: No such device error when deploying a camel-cache route

Issue

When we tried to deploy a camel-cache route we were getting following error:

15:04:49,019 | WARN  | xtenderThread-48 | CacheManager                     | 186 - org.apache.servicemix.bundles.ehcache - 2.5.1.1 | Creating a new instance of CacheManager using 
the diskStorePath "/tmp" which is already used by an existing CacheManager. The source of the configuration was InputStreamConfigurationSource 
[stream=org.apache.felix.framework.util.WeakZipFileFactory$WeakZipFile$WeakZipInputStream@51b490b4]. The diskStore path for this CacheManager will be set to 
/tmp/ehcache_auto_created_1391958289019. To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a 
separate ehcache configuration (ehcache.xml) for each CacheManager instance.

We did not configure EHCache ourselves so everything was default.
