we are experiencing out of sync problem between master and slave (we have one master and multiple slaves).
Master and Slave nodes have the same version number, but when a document on Master node will be deleted, the Slaves sometimes still have this (removed) document in the index.
Whats the best way to "debug" / analyze such out-of-sync/replication issues? In catalina.out File i just see the message on slave "in sync with master" but thats not true.
Currently we have solr 4.10 installed (we cannot update because of typo3 solr-connector which requires 4.10)
Kind regards and thank you for your help in advance
