> We have 5000 clients, so I changed number of revisions to 30 as per your document. But not solved the issue.
The more past revisions that you keep, the better the SEPM will be able to provide smaller "delta" definition updates to SEP clients that are farther out-of-date.
If you have ample bandwidth and can handle clients that are out of date by a week or more downloading full definitions (up to 200 MB) then reduce the number of past content revisions to 20, rather than 30.
Also make sure that the SEPM database is not keeping old client logs for a long time- that can also consume space.
Hope this helps!
