No, nothing has changed in the web interface for posting since November 3.

The good news here is that I see several HTTP processes each trying to use
100% of the CPU -- and collectiving using up several minutes of CPU.  They
seem to be hung.  That's not good news per se, but it makes hunting down the
problem a lot easier when the symptoms are so visible.  My guess is in a
regex with exponential backtracking time or something.  I'll have to dig more
and try some testing myself.  I'll let you know when it's safe to try again.


Could be me of course.

I'm almost postive it's not you.  Thanks very much for reporting this, and I
see from the form logs exactly how many %0A's (newlines) you used and how many
times you tried to narrow down and isolate the problem -- which I really
appreciate, as it will make my job easier in fixing the problem.
