Jose, While running the strace I noticed the non-root user could not create the file in /tmp. Indeed the file permissions on /tmp were 755 in stead of 1777. I changed the permissions and it works like a charm.

Having a backtrace of the executable when it hangs could be interesting. Also, you could send me directly a strace of it running (os speedy-cgi-perl, not smokeping) Thanks, -- Jose Carlos Garcia Sogo [EMAIL PROTECTED]
