We have already seen a few instances that it was incorrectly attributed to this issue as the root-cause.\r\n\r\nHence, can you pls add the exact scenario / use-case that this issue is seen in the description so that it is clear for anyone looking for similar issues.\r\n\r\nAs we discussed we are using boltdb from v1.9 and we haven't seen any such issues till now. As @aboch mentioned, based on his investigation, it is currently seen in a DinD setup on a CI environment. Is that your observation as well ? If not, it would be good to mention the scenario."}}
