A common failing is understanding that unix like systems are not 
originally single-user boxes.  That means that just because your box 
has X amount of resource it does not  mean that any single process can 
use that much resource.  In particular, check the memory resource 
limits of your process that is running the export.

Anyhow, did your export get any tickets out or did it die while 
exporting the other info like users list and configs?

I've found that it helps to purge the user list of owners who do not 
own any tickets (be sure not to delete the root user, or any privileged 
user).  You can do this with a left join on the tickets table on the 
owner id.  I do this after purging dead tickets (we get a boatload of 
spam to our abuse@ queue).
