Upgrade Solaris 2.6 to 2.8 and got memory fatal

Hi All, After upgraded my Sun OS Solaris 2.6 to 2.8 and I can not start Informix. I got the error messages, see below. I know one db chuck is not accessable. But I believe, I still able to bring the engineer online right? Any input I would be appreciated.
