[galaxy-dev] negative user data usage

Hi,

Today, I found out that one user in our local galaxy installation (the administrator user) has a negative disk usage. - Reports shows : -72780720701 bytes - Galaxy history shows: -1%

Does anybody have suggestions on what might be causing this and how to solve it? There is about 660 Gb of data in the histories of that user, but it was more before. I believe it happened after some histories were deleted and there was a message of one of them being shared.

Best,

Geert
