Demo server encounters downtimes and the log output before the crash is always the same:

Threads are going to be renewed over time to try and avoid a probable memory leak.

==================================================
It seems that the problem is in BTE.
BTE does not take care the case of misconfiguring the CSVDataLoader, that is, BTE does not raise an exception when someone says to CSVDataLoader to read a column that doesn’t exist in this CSV.
Moreover, default configuration for CSVDataLoader in DSpace:
https://github.com/DSpace/DSpace/blob/master/dspace/config/spring/api/bte.xml#L284
has some random numbers (like the 31 that is mentioned in the error you sent) for the column indices.
Thus, my guess is that someone is trying to upload a random csv file in the demo dspace without configuring the BTE at all (and how could he :)), so the exception of "ArrayIndexOutOfBoundsException" is raised.
The same applies for the TSVDataLoader as well.
Another problem is that the aforementioned exception _somehow_ brings down all the webapps.
Also, this must have been launched from the UI, so we should make sure that the error bubbles up properly to the UI.
