Hi Bruce,


thank you for the feedback.


Have you posted it under "#use" ? :-))))

Just a follow up…it was embarrassingly stupid. You know how you can stare at an error in
a line dozens of times and not see it? Like the ‘#' commenting out "use Apache::DBI” in
your file ...

Hi Bruce,

I'm just guessing, but this sounds much like reusing or double using of Oracle db handles,
context handles or statement handles.

You have to have a look at the bookkeeping of the handles per request. Also forking of the
childs may byte you.
You must ensure that db handles are ONLY opened in the child process doing the work and get
closed properly.

With DBI in use you can use the variable DBI_TRACE to get extensive log. Google for that in
combination with mod_perl.

Just some hints.

Best regards
