As I recall you were exporting to the database; is that still true?  If so, 
what does the server's disk I/O load look like?

When database export is enabled, IM (the server itself, not the database) 
writes much more to disk than normal, as it stages data for export.  Because 
there are significant differences in the way IM interacts with the disk on 
Windows versus Linux, it's possible that polling on your new server is stalling 
while waiting on disk I/O.  That typically manifests as short-term packet loss, 
since IM isn't counting responses that it perceives as 'too late'.

We have a special built-in probe used to debug such problems; you can find it 
under Experimental -> InterMapper.  Create a device with that probe, and let it 
run for a while.  Then take a look at the status window and please send the 
results in an email to support.  We'll use the resulting support ticket to 
respond to you once we've taken a look at the data.

A note for others reading this: do not use the InterMapper probe pre-emptively 
as a diagnostic tool.  It's marked 'Experimental' for a reason, and is designed 
exclusively for debugging specific problems.  It doesn't produce meaningful 
results on a normal IM server.
