panic: DBI active kids

Environment:
Apache 1.3.33 on Linux Fedora 3. Firebird database, DBD::InterBase,
with Apache::Session::Store for session info.


At seemingly random intervals, the browser gets a raw error page
including text similar to this:
-----------
panic: DBI active kids (4) > kids (2) at
/usr/lib/perl5/site_perl/5.8.0/Apache/Session/Store/Firebird.pm line
77.
-----------
The code at line 77 the code is '.... execute';

The application also uses Firebird for the transaction (shopping cart)
data, so I don't know whether it is the session activity or the
product/purchase information activity that causes this error.

Can anyone help me understand what is going wrong?

Thanks,

Dennis McFall
