Hi, Actually, we have two different versions (current and beta) of the software, working against the same ZODB. We are just developing new features on top of the beta version. Fearing that it was due to some changes done by a programmer we have disabled the "beta version" but the growing of the DB is still there...and since our last email we've got 5GB more (71GB now) .... We are a bit worried since the disk space is 102GB and the application is widely used here at CERN and for outsiders too.
So, up-to-now we are afraid that it is not a problem with any modifications in the code....and no clue about it. We are trying to pack to see the difference with the data.fs file. Jim, I am still running your script "class_stats.py".....and it seems it is going to take a while yet.... Thank you so much for your help. More ideas appreciated!
