Well I5/OS is running in MPM mode so...

No the file exist but it seems the first time, the module couldn't
access the file system (I didn't know why and wait more informations
from IBM)

Errno 3025 is file/dir not found and as you can see, the second time
it works so it's really something related with I5/OS implementation

Well the Apache instance exit with error message in its job log (i5/OS
job journal) about error during post-configuration. And if the first
time the i5/OS can't stat the, I suspect it fail
and error when trying to read it.

yes Apache 2.x implementation on i5/OS is a different beast than stock
Apache 2.x and without help from IBM labs it will be difficult to see
what could be done.

BTW, I started to work on the v5R4 UTF mode and will commit more tomorrow
