But if you are allocating memory for cache entries that are constantly expiring and being purged, the pool will continue to grow until the server is restarted. The pool would end up with stale memory that the system has no way of reclaiming outside of restarting the server. NetWare doesn't have the concept of a child config pool since there are no child processes and therefore no need to use shared memory. Simply restarting a child process is not an option. On NetWare it is all or nothing. Apache is either up and running or not. If you tried to shutdown the process to reclaim memory, you lose the web server.
Hmmm...
Could apr_reslist_* help here? Perhaps if the memory was allocated from a pool which was cleaned up periodically using apr_reslist_* (where "cleaned up" could mean duplicate all fresh cache entries in the pool to a new pool, and trash the old pool).
