Following is an 'onstat -g seg' output, showing all Informix shared memory segments: In general, ‘key’ values in ‘onstat -g seg’ output are sequential numbers.

This will fragment the address space and reduces the maximum size of shared memory segment that could be attached. But I cannot get a second process to attach that same existing segment.

If you are using the correct SHMBASE value in your ONCONFIG file, then consider this message informational only. The problem occurs when a DLL has a base address somewhere in the middle of the IDS shared memory segments.
