Quote:> Also, the cancel moratorium dropped traffic volumes substantially.
And caused a problem itself! In the INN FAQ, it states that if the
server is spending most of its time doing I/O, a primary culprit is
the control.cancel group as there are tens of thousands of articles in
this group per day, the largest by far. I recently rm *'d the group
from our server (I typed ls in the directory, it hadn't come back with
the results after half an hour, so I killed it!) as the machine was
spending 80% of its time in I/O wait. This is because unix slows down
a lot when accessing a directory with a lot of files in it as it walks
the massive directory tree.
The rm * took over 15 hours to complete. I/O wait went down to 2%. No
wonder expires were taking more than 24 hours to complete!
All sorted now thankfully.
