Camel not able to pick 0 byte file

Question

I have camel configured to pick file from ftp. but where any empty file is placed it fail to pick it and log same event continuously:

2015-07-14 19:53:11,005 WARN  [org.apache.camel.component.file.remote.strategy.FtpChangedExclusiveReadLockStrategy] (Camel (camel-1) thread #0 - ftp://abc.com/responsefiles) Cannot acquire read lock within 20000 millis. Will skip the file: RemoteFile[REFUND07102015.141730.csv]

my camel config is :

sftp://[servername]/responsefiles?username=[username]&password=[password]&readLock=changed&readLockCheckInterval=5000&noop=false&preMove=.processing&move=.done

Answer 1

You likely need to configure readLockMinLength=0 to allow picking up empty files. See more details at http://camel.apache.org/file2
