So I've got various vmcores here from kmem_malloc failures.. I already
know that it's an excess of mbufs that's causing the crash, I'm just
trying to figure out what the mbufs contain so that I can try and figure
out where they came from..
Currently I'm able to get at (uma_zone_t)zone_mbuf, but I'm unsure how
to get to the actual mbuf data from there. I've tried looking the the
uma_keg, etc. No luck so far. Is there anyone familiar with these data
structures that could point me in the right direction?
(kgdb) p *zone_mbuf
$66 = {uz_name = 0xc076d6d1 "mbuf", uz_lock = 0xc1048108, uz_keg =
0xc1048100,
uz_link = {le_next = 0xc1047180, le_prev = 0xc104812c}, uz_full_bucket = {
lh_first = 0x0}, uz_free_bucket = {lh_first = 0x0},
uz_ctor = 0xc05068f0 <mb_ctor_mbuf>, uz_dtor = 0xc0507040 <mb_dtor_mbuf>,
uz_init = 0, uz_fini = 0, uz_allocs = 137806761, uz_frees = 136018292,
uz_fails = 136, uz_fills = 4, uz_count = 128, uz_cpu = {{
uc_freebucket = 0xc73a8c48, uc_allocbucket = 0x0, uc_allocs = 0,
uc_frees = 0}}}
Thanks!
