Here's some very minimal log for you.

piv026$ pvfs2-set-debugmask -m /pvfs2 cancel
piv026$ export PVFS2_DEBUGMASK=cancel
piv026$ mpiexec -nolocal -n 1 perf -n 1 -s 1800m pvfs2:/pvfs2/foo
job_timer: expiring job!
job_timer: expiring job!
#np size   chunk  write no sync- read no sync-- write sync---- read sync-----
#   (MB)    (MB)  (MB/s)         (MB/s)         (MB/s)         (MB/s)
1   1800.0 1800.0  39.09 +-  0.0  34.30 +-  0.0   0.00 +-  0.0   0.00 +-  0.0

The server log has the same thing:

piv026$ cat /tmp/pbstmp.48647.nfs4.osc.edu:17001/log/pvfs2.log 
job_timer: expiring job!
job_timer: expiring job!

Methinks you need more debugging.  Try it on your machine and see
if you get the same thing.
