问题The
The VSE on-demand scanner (ODS) architecture was improved in VSE 8.8 to be multi-threaded, so that ODS could complete in much shorter times.To facilitate scanning, one pool of threads reads from the hard drive to build a list of file objects to scan. Another pool of threads removes items from that list as the file object is scanned. Unfortunately, the list of files to scan tends to be populated faster than the scanning threads can remove items from the list. So, depending on the number of files to be scanned, the list can grow in memory to be large. There is no limit to the size of the list, so it can grow to multiple gigabytes in size. The following three things influence the size:
Restricting the ODS performance threshold to Very low thread priority limits the number of threads used by the ODS, but it might be insufficient to avoid this issue. 系统更改You installed VSE 8.8 and configured a scan with a large volume of files. 原因The list of Files to scan grows faster in memory than the list can be reduced by files actually being scanned.

解决方法You can control the amount of memory used. Configure ODS to target specific folders or files, rather than an entire volume or drive. In these scenarios, the number of files to be scanned is lower, and the list of files to be scanned does not grow too much. This method requires multiple ODS tasks to scan the same volume because you are effectively breaking up a large task into smaller, more manageable, tasks.
