Issues following 9.3.5-p1 upgrade to 9.7.0-p1 Windows VMware environment

[rsmith at osc.gov.on.ca]

We have been running Bind 9.3.5-P1 on Windows 2003 guest in VMware ESX 3.5 
environment for many years with no issues. Following an upgrade to Bind 
9.7.0-p1 we are experiencing a couple of issues. No Bind configuration 
changes were made to config files other than the allow-query-cache, 
additional-from-auth and additional-from-cache statements so that queries 
worked in the new version. The errors are occurring on multiple Bind 
servers on different Vmware ESX hosts.

On a regular but random basis we are getting the 2 socket error messages 
logged. I have not been able to determine what is causing this to occur 
nor reproduce at will. 

.\socket.c:2444: unexpected error:
SOCKET_RECV: Windows error code: 1236, returning ISC error 54

We are also getting a poked timer error logged consistently soon after 
Bind service start and infrequently after that. 

*** POKED TIMER ***

Any suggestions / solutions would be greatly appreciated.
