I took 2008-06-23, verified that the patches are in, compiled and started.
Today my disk ran full again. Half of the files are status "Insufficient diskspace", the other half is "Erroneous".
CheckDiskspace=1
MinFreeDiskSpace=10
I'll change it to 30 and wait again, to be sure the limit is honored. Right now I'm not sure whether this is the emergency brake by the check with PARTSIZE.
