Problem after applying y2k patches to aix 4.1.5

1. Informix problems afters Y2K Solaris 2.5 patch

Since I did the Y2K patch for Solaris 2.5 on a Ultra Sparc 1 system,
Informix 7.22 refuses to startup properly.
Anyone experienced a simular problem? Any suggestions?
Attached some system information and the relevant part of the online.log
