system is loosing disk space at extraordinary rate - SOLVED

[Philipp Rusch <Philipp.Rusch@xxxxxxxxxxxx>]

We solved it:
It was the NETSERVER function of V4R5 that caused the memory leak ...
ending the server for netserver shares gave us back the most of the temp space
which has been used up during this week again.

We are using the /HOME directories of every user to temporarily store STMF's
when he going to print images of the articles/details he selected in a subfile 
(CBL)
program. Somehow the space of these files did never make its way back to OS/400.
So it summed up during the day to about 300 megs .. and on and on ..

We installed C2050450 today, installed the HIPERs and the DB-group PTFs
and hopefully this was it.

A nice weekend to all, Philipp Rusch
