I have powerpath 5.7 running on vSphere ESXi5 with the RTOOLS and license server running on RedHat Linux 5.6.  I am getting inconsistent slow responses, errors like Host not found when running rpowermt commands.  They work sometimes but for the most part they don't.  On one of the ESX host I am seeing the following messages when trying to run rpowermt commands:

sfcb-sehost_omc:  Timeout waiting for response from provider.

Has anyone seen this problem and if so please assist.

Thanks...
