Okay, since you said this I haven't noticed any problems with sunpal7
(except that it is currently off-line), but your other system linuxpal
<rpiw4n3f> continues to take 8 minutes to answer most (or all?)
queries!

I would like to learn more about what is going on with that guy. Could
you check for the processes CPU and memory usage, maybe see if it has
an unusual number of files open or anything like that? And look in its
tahoe basedir for log files, especially incident report files?
Assuming that the tahoe basedir is ~/.tahoe, then those files would be
~/.tahoe/logs/twistd.log and ~/.tahoe/logs/incidents/* .

Thanks!
