Enterprise server not restarting

We have a UNIX ES, AIX6.1 recently patched to 6100-06-03-1048. Since patching, services cannot restart. JDE Xe, B733
SP23_S1. Any idea what may be causing this? Logs below:

Hi,

Does your "jde" user (whatever its name is) have the
proper permissions to read and execute under
/jdeb7/oneworld/b7333?

After stopping services, did you run rmics.sh or
similar command to release ipc resources?

mmm it might be a wild guest but why don't you try to change the parameter startIPCKeyValue on your server's jde.ini

[JDEIPC]
ipcTrace=?
maxNumberOfSemaphores=xxxx
startIPCKeyValue=xxxx
