As it happens, I'm processing one row at a time. Additionally, the out of memory error happened originally without having LongReadLen set at all. I've been doing some tracing for this, and found that the issue is with a third party module that I was using, that creates a db handle as a derived object (terminology?? I'm not an OO programmer). Turns out the reason I was using the module no longer exists and I can do the connect directly, which eliminates the problem. Thanks for the suggestions and observations. -- Bob McGowan
