msg during start up of memory and shmem

Hello all, I have a question about a msg in online.log during start up. My shvirtsize is 491520 and onstat - reports memory allocation of 1,292,456. The hp-ux 11.00 shmmax is 1.6 gig and maxtsize_64 (code space) is 1.6 gig. I would think I have enough mem allocated in unix as well as enough allocated in IFMX. Why is IFMX unable to allocate a single mem segment if unix is allocating 1.6 gig to a 1.3 gig process? IFMX 7.31 uc2a. KAIO is on. tia!!! onstat -m after re-start:12:39:45 Shutdown Mode 12:39:46 Quiescent Mode 12:39:55 Informix Dynamic Server Stopped. 12:40:11 Could not create single shared memory segment with resident and non-resident partitions.

There are probably kernel parameters which limit the total size of a single shared memory segment. I'm not too familiar with HP-UX but if you know how to explore the kernel settings you could start there until someone who knows what they are talking about chimes in. adiosadios wrote in message <969shv$e7i$1@news.xmission.com>... > >I have a question about a msg in online.log during start up.
