> Affects Versions: Segment Tar 0.0.10
> Reporter: Timothee Maret
> Assignee: Francesco Mari
> Fix For: 1.2, 1.4, 1.6, 1.2.21, 1.5.13, 1.4.10

> 1. In a setup composed of two instances (primary, standby) configured with a custom blob store (File blob store).
> 2. On the primary instance, set/update a BINARY property of an existing resource with > 2MB binary.
> 3. Observe that the standby instance does not fetch the binary and instead, enters a loop detecting the missing binary upon comparing node states.
> For example, the following stack trace would be printed every 5 seconds on the standby (the polling time is 5sec).

> This behaviour only occurs when _updating_ a binary property with a new binary which length is equal to the previous binary and only on setups involving a custom blobstore.
