48 oninit processes, when informix started

Hello: We are running Informix Dynamic Server Version 7.30.FC4. recently we noticed that when the system was rebooted, 48 oninit processes were started. That is a lot. Could not figure out why so many. need your help!

You have NUMAIO vp's blank. By doing this it uses the default. Which I believe is 2 per chunk, without checking the admin guides....

If this is the case every reboot adds new (may be 12) oninit-processes. Another advice: Don't leave NUMAIOVPS blank if you are using KAIO. This means ids is taking 6 aiovp's. Set it to 1 instead. hth martin
