Hi, In the current implementation of DefaultStreamCachingStrategy (Camel 2.12) the default spooldir is set to '"${java.io.tmpdir}camel-tmp-#uuid#"' Which results in path like '/tmpcamel-tmp-XXXX', unfortunately the technical user starting our application is not allowed to create directories on root level which causes IoExceptions later on. To bypass this problem we currently configure a custom spool directory, but I suggest that the default path should be changed to something like '"${java.io.tmpdir}/camel-tmp-#uuid#"' Now the spool directory will created inside the temp-director, not parallel to it.
