Hi Perrin,
Does Apache::DBI work right with Apache2+mod_perl2?
Yes, but there may be a bug in how it checks to see if the server is restarting.

Perrin is right. But fundamentally, I'd say that you're confusing
'local' and 'my' variable scoping:

I believe I am using my declaration rather than local. I also tried
explicitly disconnect but still have same issue. Since it only happens in
parent/child processes, I don't know a good way to debug parent/child, nor
reproducing the same error using a simple program. Can you guys help me

I'm afraid I'm out of my league. I just noticed the following comment on
the Apache::DBI man page:
Edmund Mergl was the original author of Apache::DBI. It is now supported
and maintained by the modperl mailinglist, see the mod_perl documentation
for instructions on how to subscribe.
Well, you are on the modperl list, so that means you. :)
Xinhuan, the error is harmless, but if you're concerned about it I would
try turning on debugging to make sure the connection is not being cached.
Do this:
$Apache::DBI::DEBUG = 2;
And then watch for a message like this in your log:
@perl.apache.orgmailto:modperl@perl.apache.org
modperl@perl.apache.orgmailto:modperl@perl.apache.org

Did this solve your problem?

Hi,
I have apache 2.2.23 statically compiled with mod_perl2 (prefork). perl binary
is 5.10.1. In startup.plhttp://startup.pl/ file there is call

A few questions:
Precisely when do you get this error? When startup.pl exits or before?
Can you send a copy of your startup.pl file?
You get exactly the same error on startup and shutdown?
If PerlRequire startup.pl is commented out, do you still get errors?
Do you get errors when
