In the customer environment were 321 imports saved. The module was not opened and a 504 Error was displayed. I have seen that the logfile /var/log/univention/ucs-school-import/gunicorn_error.log has logged even more entries than the 504 was already reported. So I reduced the database entries and the module is shown again. Currently the problem will not occur so often, but with time the entries will have a higher value for many customers. An automatic reduction of the entries or an increase of the timeout time should be implemented. How to solve the problem manually see first attached ticket Notice 16

Happened in another customer environment.
More and more customers are complaining this.

When working on this, also check bug 53383. It may be a duplicate or it may add an additional problem (many OUs).
And again in a customer environment.
To point on that again. There are some environments where the webimport is absolutely essential. Bildungslogin f.e. In these environments a lot of imports take place and the database grows fast...
The reduce and cleanup old import jobs, could fix the timeout issue. Here is an article to use a py script to clean older import jobs. Workaround und: https://help.univention.com/t/how-to-reduce-entries-of-ucs-school-web-import-database/16222#optional-step-delete-old-import-jobs-14

Looks good to me: Old imports are deleted if configured -> OK Max number of shown imports in the umc module can be configured -> OK Sort order changed -> OK jenkins -> OK
