From client start upload to server several files (big - more than 100MB and
small – less than 1 mb).

rsync: [sender] write error: Connection reset by peer (104)
rsync error: error in socket IO (code 10) at io.c(820) [sender=3.1.2]
After this error on disk we can see next files:

.corebases.cab.GjiXui <- temp file, on this file has been disconnection
-rw-r--r-- 1 replicator replicator 43010386 Oct 16 23:14 corebases.cab <-
old file that was on the disk before rsync start
On the next rsync start leads to that the remainder of the file is filled, file
bases/kavkis2015mr1/KSM/corebases.cab uploaded again, temp file is deleted,
rsync log:
*deleting bases/kavkis2015mr1/KSM/.corebases.cab.GjiXui
It is correct.
But sometimes we have wrong result, on the disk file is corrupted.
In first time we have disconnect:
