Run away process

we are using cloverETL server 2.9.2 hosted on a windows server 2008 64 bit in a 64 bit version of tomcat 6.0

we need to run about 80 graphs in series and are using the graph listener feature. Everything works fine when we are running a small test set, a few 1000 records, but have not been able to run everything on a full set, a few million records. during the run a graph will “hang” and just keep running and never finish. if i kill the graph the tomcat process on the server acts like it is still going and takes about 13% of the cpu. the next time a graph hangs and is killed it takes another 13%. to recover this i have to restart tomcat. is there a better way?

This issue has been solved using our customer support system.
