got an issue

Hi guys,

I use this script on two of my nagios (different site)

one is now in use and with a very good reply.
another one has a big issue that after i installed basic component and vmware tool kit.this script can run with out error but only a time out output.

./check_vmware_api -H xxxx -u root -p xxxx -l cpu
CHECK_VMWARE_API UNKNOWN – plugin timed out (timeout 30s)

could anyone give some suggestion on this?
