Hi,

Just a quick ping on this issue, it is still happening and we are slowly
filling up the disk again. Is seems like we will have to plan a remount
within a month given the current graphs. I will be back with info once
we have remounted it, running you suggested scripts before and after.

Is there anything else I can do to get more debug information?

Regards,
Palle
