[Mimedefang] Perl DBI problem stops mimedefang from loading?

I notice this problem does not occur if I do not specify a limit for 
MX_MAX_RSS and MX_MAX_AS when running the multiplexor.  Why?  I was 
trying to specify MX_MAX_RSS=30000 and MX_MAX_AS=60000 and it gives the 
error below.  I was using these on an older 32 bit single processor 
server without a problem for years.  I'm now trying to migrate to a 64 
bit SMP server and I can't specify these max values without it failing 
with the following error.

Does anyone know what I'm missing?
