Permissions, perhaps? Running it using syscalls might provide some clues.

I'm having issues trying to exec uv from PHP on AIX. Things work just fine in Windows (Apache or IIS) or Linux (Apache) so I know my PHP syntax is fine. On the AIX (5.2 uv 10.2.7) box: Using PHP, I can exec 'echo 1 + 2 | bc' and get 3 I can run this at the shell as user nobody: 'cd /u2/uv/HS.SALES; /u2/uv/bin/uv "display 42"' I can get a CGI script to return 'cd /u2/uv/HS.SALES; /u2/uv/bin/uv "display 42"' correctly With PHP, I can't exec ' /u2/uv/bin/uv "display 42"' (after a chdir). UV throws this error (into the Apache logs): An error has occurred during uniVerse initialization Please contact the system administrator Error code: 4 22 The codes translate into: 4. System V semaphores are probably not configured in the kernel. 22. (EINVAL) Invalid argument. Here are some examples of invalid arguments: dismounting a nonmounted device, mentioning an unknown signal in signal, reading or writing a file for which seek has generated a negative pointer. EINVAL is also set by math functions. Has anyone else bumped into this? IBM support suggested it might be an issue with SIGTTOU but this seems unlikely to me - especially for a one-line command. PHP is a bit outside their bailiwick.
