As far as I understand what you are doing, this is not a bug in Embperl.

Embperl caches the compiled Perl code you pass to it via Execute, so Embperl
needs to know when to the source changes, so it can recompile the Perl code.
This is done by the mtime parameter. Anytime your code, you read out of your
database has changed, you must change the value you pass to mtime. If you
don't change mtime when the source has changed, Embperl uses the old Perl
code, with the new HTML source, which couldn't work of course. (Also any
container must have a unquie string for inputfile, because Embperl uses this
text to distiguise the sources you pass to it).

If you are not able to provide the mtime value that changes everytime when
the source changes, that pass undef to mtime, this would recompile the perl
code for every request, but this will slow down your page
