RTRR: Error with (-2)

[bikkuri]

Hi

i have setup an RTRR between 2 TS-879U-RP.
There is a schedule should sync every 10 min. between the 2 folders but
i have now some troubles with the sync.
the sync stops with error (-2)


Information 12/01/2017 08:46:52 System localhost [RTRR Job] (Sync) Job ucp-tuca-nb-01 <-> ucp-puca-nb-01 failed: Program has encountered an unexpected error! (-2)
Warning 12/01/2017 07:23:38 System localhost [RTRR Job] (Sync) Job ucp-tuca-nb-01 <-> ucp-puca-nb-01 failed: Program has encountered an unexpected error! (-2). Begin the 1st retry.

these happens only on some kind of files, like *.ova *.vmdk but if just create a *.txt file for a test it will sync.

Does anybody know what this error code means? i couldnt find anything.

Assume obvious things like have available space?
How long are the filenames?
Is it only on bigger files it crashes?
Create a new RTRR job to a new destination folder with a ova/vmdk, does it work?

[bikkuri]

we have plenty of space left and about filename it is not a problem about the length.
Looks like that only bigger files has this problem, i created a new RTRR job it works first just fine but at 35% it stops the sync with the same error.

Assume you're on latest firmware.
Any more luck with RSYNC on these big files?
