Stefan Roos commented on CAMEL-10782:
-------------------------------------
What was apparrently happening was that, when file was created it was zero in
length. So camel-ftp went sleeping for short time, because it could not get
readlock (minsize 1). After that it tried to reCheck the file, but for some
reason from the server root, / , and not from users home, /home/testi/. File
count which was reported by camel-ftp, matches the count from that servers root
(home dir count would be less than 10 files/dirs).
I found a way around this by setting source directory to "./" like this:
<from uri="sftp://testi@infra:22/./?password=passu&.....
With that kind of from URI it does seem to work normally.
> SFTP: cannot get files from users home with readlock changed

> Camel cannot fetch files from users home directory when using
> readlock=changed.
> Route from URI is defined like this:
> <from
> uri="sftp://testi@server:22?password=password&include=PSOP_123-.*\.(xml|pdf)&delete=true&readLock=changed&readLockTimeout=360000&readLockCheckInterval=180000&readLockMinAge=10s&maxMessagesPerPoll=100"/>

> User home directory contains only 1 file, which does match to include

> When placing the files to a subdirectory in users home, this does not happen.
