I am fairly confident I have found the cause. It was my fault, not rsync's :-( I run gimps (Mersenne prime search) in the background at lowest priority. Except that during a system upgrade last month I made an error with the gimps startup (in rc.local) with result that it was running at priority higher than my cron jobs. Compounded by me allowing gimps to use a large fraction of physical memory overnight if it wants to - though whether it actually does is unclear. I had forgotten that the cron rsync jobs also run overnight. rsync was almost certainly reporting a genuine timeout caused by it being starved of CPU time and possibly memory. I run the large rsync backup only once a week, so too soon to be sure the problem is resolved. However this week's backup ran ok via cron for the first time so looks promising. -- ------------------------------------------------------------ John Hunt Stokesley, N Yorks, UK URL: http://www.yoredale.uklinux.net/ ------------------------------------------------------------ -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
