Yep!  This week on 2.6.32-41 I noticed apcupsd hang after about a day,
followed by the 'control queue full' errors an hour later.  That was
with the patches suggested in #631287 applied, just in case they made
any difference to this.

I already tagged affected versions in the BTS;  the first report of this
was on 2.6.17 and I myself recall seeing it as far back as 2.6.26.


I hadn't been able to test the UPS on a 3.y kernel until this week.
Right now I have the UPS hooked up to a new server running 3.2.0-2-amd64
(Debian 3.2.12-1) to see if it recurs.

Then in a few weeks, I'll be taking the original hardware (on which the
issue was easily reproducible) out of production use, so I can try 3.y
kernels on that too.  (Until now, I couldn't try 3.y kernels on that box
as it needs to run OpenVZ containers).
