I had the most frustrating dasBlog issue over the past couple of days:

I suddenly found myself unable to post anything on my blog.  This coincidentally happened at the exact same time my hosting provider had me try a web.config change to alleviate some session/viewstate issues I was having.  I would try to make a post, get no errors, and be returned to the front page and see that my post was missing.  Referral logs were strangely missing, and the dasBlog event log was also strangely empty.  The only thing I could get a vague error message from was trying to post a comment.

Apparently, my "Anonymous Asp.Net user" had suddenly hit its disk-space quota.  I don't know if this quota was created recently or not.  It seems odd indeed that dasBlog would cruise along and never report an error when it's out of disk space.  I wonder if this is something dasBlog is doing or something that's happening because of the hosting environment?
