Hi Gian, The reason might be if we delete any intermediate snapshot from CloudStack, the file will not be physically removed from secondary storage(scenario 2 as specified in the below article :),it will keep till you removed the last snapshot. In case of xen, it maintain the snapshot chain ,once it reaches the limit, then it will perform full snapshot.
http://support.citrix.com/article/CTX135172 You will see intermittent issue if the snapshot chain lost the its chain info due to manually deleting of files form secondary or corruption of vdi file or due to any corner cases where deleting one file instead of another file/restarting of ms while snapshot operation in the middle might result data inconsistence in between cloudstack data and Real data.

I recall (quite a long time ago), there was a bug where volumes and snapshots weren't getting cleaned up correctly.
