------- Additional Comments From chrisd@pearsoncmg.com  2006-12-28 14:57 -------
The patches attached so far don't completely solve all the problems
identified in the report.  For the latest, see the first three patches
(1tidy, 2misc, and 3pools) for httpd trunk in:

http://people.apache.org/~chrisd/patches/mod_dbd_pools_groups/

These should be applied sequentially.  The third (3pools) patch is the one
that actually addresses the original issue from this report.  It makes use
of the fact that MPMs (should) call apr_pool_destroy() on the pool they
pass to the child_init hook functions, when each child process exits.  However,
they don't call apr_pool_destroy() on s->process->pool in child processes.
This allows us to work around the interaction of APR reslists and memory
pools at pool destruction time.
