I'm running an rsync command from cron every 15 minutes that gets a permission error after some time.

I can see from my ssh config file that I'm set for 6 tries which is why the script is failing. How to get around this issue? Have to run the script from the command line to get the script to 'work' again.
Been recommended not to change the retires variable.

See the error below. I will need special permission to edit the ssh config file if that is the suggestion. I tried adding this to my command but didn't resolve the issue - -o 'IdentitiesOnly yes'

/usr/bin/rsync -avz --stats --progress -e "/usr/bin/ssh -p 2022 -i /home/fkbin/.ssh/lrsyncprd -o 'IdentitiesOnly yes' " --delete --out-format="%f %t" /app/interface/unit1/ fkbin@lctcvd0266:/app/interface/unit1/ 1>> /app/logs/unit1.log 2>&1

As what users are you trying to run the rsync script as?

I'm using fkbin to run the task under cron. Works first couple of times then filas with permission error.
Works fine from console when I'm logged on as fkbin.
