Update Manager 4.1 (ESXi 4.1) ( '[Errno 12] Timeout: '))

Can anyone offer some assistance?....

I'm having trouble staging the patches to the ESXi hosts.  The patch definitions do download successfully.  The VUM DB is on a separate SQL server, and the DSN is set up correctly.  The vcenter server is open to the Net.

I have enabled the esxupdate log on the host which logs the below error - though I'm not sure what this log means. 

ERROR:  esxupdate: An esxupdate error exception was caught:Traceback (most recent call last):   File "/usr/sbin/esxupdate", line 257, in <module>   cmd.Run()  File "/lib/python

Thanks!
