We're having a strange issue on one Distribution Point (hosted on WS 2k16 Server like all the others) where the pending packages are failing to get distributed. Though there are no evident errors in the distmgr.log of the Site Server, it looks like the distribution is attempted to only one drive (where the free space is exhausted). And even though there are other drives available the distribution doesn't seem to be failing over to the others.
How can we troubleshoot? Where can we look for further information on what could be possibly wrong?
