You’ll need to look at the solr logs on the machines hosting the collection’s replicas. There should be something more informative there.
Is the collection even available for on the target? Can you search anything there? And what’s the reason the collection is being reloaded? If you have “schemaless” mode enabled, updating the schema as docs are being indexed would cause a collection reload, or if you’re updating the schema via the APIs. Are either of those possible?
