I've come across a weird problem which I'm trying to debug at the moment, and was just wondering if anyone has stumbled across it too:
I have an active-passive-passive configuration (1 Source cloud, 2 targets), and NOT all the documents are being replicated to the target clouds. Example: 3 docs are being pushed/indexed on the Source cloud, S1, S2, S3, and only 2 docs can be found (almost immediately) on the Target clouds, say T1, T3. It's imperative to notice, that consistency is preserved, so all the Target clouds get the very same docs, and the 'missing' doc/s is/are always the same.
I feel like it's a configuration issue, but it could also be a bug. How can I debug this issue?
What log files should I examine?
I couldn't find anything in the logs (of both the Source & Target clouds)..
'solrconfig.xml' is attached (from both Source & Targets clouds).
