DPA agent times out executing DD commands

Hi

After successfully adding my DDVE system to my DPA 6.3 environment, I noticed repeated instances of these messages in the DPA agent log ‘/opt/emc/dpa/agent/logs/dpaagent.log’:

I’ve looked at the timeout values available to be set in the DPAdvisor GUI’s Admin -> Configure System Settings -> Data Collection Agents -> {my agent}, but I don’t see anything that affects how long the agent waits for the DDSH command.

When I run the DDSH command by hand in a ssh session, it executes in 12 seconds (including ~5 seconds for me to enter the password):

dpa-agent:/ # date; ssh sysadmin@ddve system show performance duration 5 min; date

What can I do to cure this problem?

Thanks
