After the upgrade to one of the latest V10 versions (SP6 and above), some customers ran into the following issue on AIX. If they use files events or PREP_PROCESS_FILENAME, they receive errors like:
U2003041 Invalid 'access' call, file name 'filename'. Error code: ('13' - 'Permission denied')
Though it was working in the older Version and the user rights are correct for these directories.
