Several times I have noticed that the CDCR action=QUEUES will return a negative queueSize. When this happens we seem to be missing data in the target collection. How can this happen? What does a negative Queue size mean? The timestamp is an empty string.
We have two targets for a source. One looks like this, with a negative queue size queues": ["uc1f-ecom-mzk01.sial.com:2181,uc1f-ecom-mzk02.sial.com:2181,uc1f-ecom-mzk03.sial.com:2181/solr",["ucb-catalog-material-180317",["queueSize",-1,"lastTimestamp",""]], The other is healthy "ae1b-ecom-mzk01.sial.com:2181,ae1b-ecom-mzk02.sial.com:2181,ae1b-ecom-mzk03.sial.com:2181/solr",["ucb-catalog-material-180317",["queueSize",246980,"lastTimestamp","2018-11-06T16:21:53.265Z"]] We are not seeing CDCR errors. What could cause this behavior?
