We are using TIS 3.2.x and have developed a process that reads data from Sybase database tables and creates two set of XML files (each set is expected to be about 500K files). We are using the tAdvancedXMLOutput component for XML file generation. The process is failing after generating about 24316 XML files with a FileNotFoundException: (File too large) message. I noted that the process works fine for smaller data sets (say upto 1000 files etc.). Is this due to any memory constraints ? can we get any suggestions on how to resolve this issue ?
