Can you re-run with
strace -f -o virsh.log ./srv/virsh
And send the resulting log file.
Also, can you run 'lsof -p <pid>' for the PID which matches
xenstored, and the 2nd python XendD process.
# ps -axuwf | grep xen
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ

You'd need to run
lsof -p 3106
lsof -p 3112

At very least output from 'xm info' will usefull
