perl "Missing version identifier"

[Andrew Zimmer]

Hi Folks,
Generally Thrift seems to be a good fit for my problem.  But I'm  
having some issues while using TServlets on the server side and perl  
on the client side.  Under high concurrent load, perl clients flame  
out randomly with the following message:

$VAR1 = bless( {
                 'code' => 0,
                 'message' => 'Missing version identifier'
               }, 'Thrift::TException' );

Most of the time, the perl clients work just fine.  On the server  
side, I can't see anything in server error logs or via breakpoints  
that indicates a problem on the server.

Thanks in advance for any help,
andrew
