I use CentOS 5.8 Final.

My situation is I running unison with cron where script below :

*/1 * * * * /usr/bin/unison >/dev/null 2>&1

and default profile like below :

root = /var/www
root = ssh://web02.example.com//var/www
auto=true
batch=true
confirmbigdel=true
fastcheck=true
group=true
owner=true
prefer=newer
silent=true
times=true

So in every minutes will syncronized www folder . My problem are :

1. I upload file with size bigger than 10 MB to www from client with user1 permission where www folder is user1 owner. file in processing uploading then unison running in that minute and suddenly file upload owner changed to root:root
2. When I editing file in www folder then I save when unison running, file owner changed to root:root where should be user1:user1

Is there anyone know about this problem?
