 Why's that?  Can't you just run
strace -f -e open -o /tmp/mylog texexec ...
instead of plain texexec?  Sure, multiple runs will mean you only ever
get to see the last log, but on a test system that should be exactly the
one you are looking for.

 Oh, and I'll second Patrick's advice:  Before letting unknown users run
arbitrary programs on your machine (and TeX code provided by the user,
even if it is just their names to be filled into some template, *does*
qualify as “arbitrary programs”), make bloody sure those programs have
no chance of ruining your server.  Double-check the validity of all
inputs, check if you can use a chroot “jail” and use the most paranoid
TeX settings with which your setup/code still works.
