Operations that change non-concurrent collections

Q:Operations that change non-concurrent

Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection’s state is no longer correct

更改非并发集合的操作必须具有独占访问权限。对此集合执行了并发更新，并损坏了其状态。集合的状态不再正确
