Something causes my Solr search index to drop and slowly reindex over and over throughout the day making products disappear.
If the Magento indexer is running on every cron run, how does it decide to mark an indexer as "scheduled" even though my Index Management settings are set to "Update on Save" for search.
Seems to be based on the changelog. Is there a magic number of changelog entries in
catalogsearch_fulltext_cl that triggers the scheduling? It's not any sort of event that i can tell. Nothing i edit and save triggers the schedule; it just seems to happen randomly.
