Nah, that ain't the problem. The problem is that with the current page numbering scheme used by Informix OnLine, you can have at most 0xFFFFF pages per chunk. On a 2k page system, 0xFFFFF * 2048 is 2GB. So lseek issues aside, there is a limitation of 2 GB per chunk on a 2k page system. --- Billski | I'm young..
