Informix: Ulimit Problems on SCO UNix

The Problem: We are running into a Ulimit problem using the Informix SE engine V4.00.UG2. We have a database that is currently sitting at the 1.07 gig barrier which is sco's standard ULIMIT. We can't add rows to this database from ISQL or home grown 4gl's they blow up with a file to large error. < this would be the reason for suspecting the ULIMIT> We have rebuild the kernel on the system to have a standard ULIMIT of 4194303 which comes out to around 2.2gig max file size.. I can create files with no problem on the system that are larger than a gig. I suspect that either Informix has a compiled in ULIMIT or SCO's write function is specially broken for informix... ;-)... If anyone has insites on this problem I would appreciate a responce.... Thanks in advance.. If you need more information let me know.. ps. The file systems are 2 gig each.. with nothing else on them.. Thanks... Geoff Kuchera geoff@winternet.com
