IDS initialization problem

Hi All, When I try to initialize a shared memory for Informix Dynamic Server (running on RedHat Linux rel.5.2, kernel 2.0.39), ONMONITOR write: Initializing, please wait.... Press any key... From online.log file I see, that "dataskip is now OFF" and "server now in quescent mode". From 'ps aux' I see that oninit -isy (10 instanses) is running. But when I make "press any key", ONMONITOR returns me to the main menu and in the bottom of the screen it writes "Shared memory is not initalized". Of course, I can't repeat the initialization of instance after that (need rebooting). What is my mistake? Thank you very much, Ruslan Satlykov.
