Missing uploaded file

After uploading the file, I added my own logical code,there is no problem uploading a small number of files,but when a large number of files are uploaded,a small portion of files be lost.
Is this question related to celery?
Do I need to make any configuration changes?

if you suspect that celery might be part of the issue, you could investigate whether there are any config changes you could make to improve performance or prevent file los. For ex, you might consider adjusting the concurrency settings for ur celery workers to optimize performance, or you might investigate whether there are any issues with task routing that could be causing files to be lost

okay, thank you I’ll try
