  @Ben, I've tried a number of things, and the best I could come up with was breaking the array of lines down and using a seperate thread for each chunk. I've tried even interacting with GC to encourage collection (I don't like doing this) but I'm not sure CF releases memory until after the r... read more »

  Ben, good post. I'll have to see if it works on my ginormous files. The conditions I'm seeing relate to CF not giving up heap space during request process, so no matter how I read it, I still run out. Sure would be nice to have a Lex/Yacc for CF when it comes to parsing files. While creating FSM... read more »

  @Ben, I'll think about the event driven approach as well. I've found his problem has more to do with when CF releases memory which I think you've raised before. I've even tried manually forcing garbage collection (a practice I don't like or recommend). Some has suggest running sections of co... read more »

You had mentioned some large datasets, but when I tried going over 10K records, I run out of heap when using CF8 Standard with a heap size of 768MB. When I monitor the heap as the test prog... read more »
