We have a three cluster Couchbase CE 6.6.3 server running on Windows 2019 Data Center. We are using it as a sync gateway back-end.
We started getting write errors with the following written to the logs.
WARNING (sync_gateway) CouchKVStore::saveDocs: couchstore_save_documents error:error writing to file [WINAPI error = 665: 'The requested operation could not be completed due to a file system limitation
'], vb:137, numdocs:55
I removed the server with the errors from the cluster, deleted the data folder, and re-added it.
The error starting happening again a few days later.
