Collection of data form 5 devices stopped

Hi,

I just noticed that collection of data from our 1x SVC and 4x Storwize stopped about one moth ago - graphs are empty.

output of load_svcperf.sh looks like:

cat /home/stor2rrd/stor2rrd/load_svcperf.out
Waiting for 29884474
Waiting for 8978564
Waiting for 9502830
Waiting for 31326444
Waiting for 24248376

another test:

./bin/config_check.sh
=========================
STORAGE: SVC: SWIZ
=========================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_dsa  stor2rrd@xxx.xxx.xxx.xxx  "lscurrentuser"
  connection ok

=========================
STORAGE: S3700-VS: SWIZ
=========================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_dsa  stor2rrd@xxx.xxx.xxx.xxx  "lscurrentuser"
  connection ok

=========================
STORAGE: S3700-OC: SWIZ
=========================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_dsa  stor2rrd@xxx.xxx.xxx.xxx  "lscurrentuser"
  connection ok

=========================
STORAGE: S7000-VS: SWIZ
=========================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_dsa  stor2rrd@xxx.xxx.xxx.xxx  "lscurrentuser"
  connection ok

=========================
STORAGE: S7000-OC: SWIZ
=========================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_dsa  stor2rrd@xxx.xxx.xxx.xxx  "lscurrentuser"
  connection ok

It happened one month ago, so I dont remember what could been changed, perhaps I did some changes related to lpar2rrd (on the same machine)

What can be wrong?

Thanks
