Are you referring to the sync_interval_timeout parameter in my conf  
file?  I'm set to sync_interval_timeout=3000

I'm also set to sync_interval=500.  Is this supposed to create a SYNC  
event every .5 seconds?  Or perhaps the subscriber is supposed to  
look for a SYNC event every .5 seconds?

Perhaps my understanding of SYNC is misshapen, and it's being exposed  
here...

Thanks for the response!
