CEPH S3 Listing Issue

HI, I have created an S3 bucket backed by CEPH and through java S3 client and via S3 object gateway am listing all the files under the bucket and always the listing is failing some times after listing 1k+ blobs or some times after listing 2k+ blobs and am not able to figure out how to debug this issue This is the Exception am getting, com.amazonaws.services.s3.model.AmazonS3Exception: null (Service: Amazon S3; Status Code: 500; Error Code: UnknownError; Request ID: tx00000000000000000e7df-005e626049-1146-rook-ceph-store; S3 Extended Request ID: 1146-rook-ceph-store-rook-ceph-store), S3 Extended Request ID: 1146-rook-ceph-store-rook-ceph-store at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1799) I tried with Boto as well and it's the same error over there, I have checked the s3 gateway pod logs but I couldn't find any relevant logs over there, so, please let me know how do I debug this issue or possible reasons for the same I have attached the java code am using for reference.
