SFTPException... Caused by: java.lang.InterruptedException

I'm having occasional problem when renaming a file. Using following logic:
1. Upload a file with a temp name
2. When file upload OK, then rename file to final name
---> 0.000001% of time I get SFTPException Caused by InterruptedException - no exception message

On server side there is no errors and file rename is successfull. SSHJ debug log does not write any errors...
I am using also keepalive like this `ssh.getConnection().getKeepAlive().setKeepAliveInterval(60);`

Here's the stacktrace:

Can this issue be related on SSHJ-library? Tested with latest version 0.32
