Hello, An our customer got a problem on RADOSGW. The customer tried to list objects on a versioned bucket with S3 API, then they got 500 server error due to FastCGI timeout. RGW's internal listing process continued over the night (approx 10hours) until they restarted the RGW. Please see attached radosgw log. The behavior seems to be similar to bug#12913, but they are using v0.94.6 of RGW. The bug should be resolved in the version. http://tracker.ceph.com/issues/12913 As we can find in the log, RGW repeatedly tried to get information for a specific object (testfile1896.txt). The object has null version and another version as bellow. Yes, versioning of the bucket was enabled after some objects had been put in the bucket. Similar condition can be found in bug#15243, but the fix only affects to deletion. http://tracker.ceph.com/issues/15243 Are there any problem remained in versioned object with null version?
