Hi, Maybe another approach will help. Can you write a little command-line test program to do the import? One that will read, parse the file, set up the ImportManager, and do your DB work, all outside of tomcat. Perhaps that will make the issue easier to pinpoint and then debug. It's certainly easier to profile (using OptimizeIt or whatever profiler you prefer) outside the servlet container.
On the other hand, if the program runs quickly and without memory leaks outside of tomcat, we probably have a more serious tomcat issue at hand.
