hello,


I've a question (maybe a stupid one). I have a problem with a box so I'm start

searching the reason of this problem. By reading the code I'm wondering what

are the circumstances under which the code panics in pool_do_get (different

sentinel values...) specifically in


#ifdef DIAGNOSTIC

     if (__predict_false(pi->pi_magic != PI_MAGIC)) {

           panic("pool_do_get(%s): free list modified: magic=%x; page %p;"

                 " item addr %p",

                 pp->pr_wchan, pi->pi_magic, ph->ph_page, pi);

     }

#endif


really thanks for any explanation/example and/or something to read on the

matter

It happens when some memory was freed to the pool and then modified after

it was freed.
