Hi,
We had issues yesterday in saving webmap.
And when trying to save as, it throws an error: "Unable to load portal/sharing/rest/content/users/xyzx/addItem status: 500"

then I found out that our Webadaptor server has 0 disk space available, so I deleted unused and old items, then tried to save the map again and it works.
So issue above was related to IIS/Webadaptor? Which log should I checked for this type of issue?
