Colleagues, good afternoon. Last 15 days the strange picture is observed.
There is a server nw65sp5 + update sp5, memories 2 Gd volume of volumes
683093. And so in current of these of 15 days is an operating time of a
server decreases Available Logical Space
Yesterday in general has fallen up to 124 Md.
Here mine segstat
