Use dtrace to find the address argument passed to `id_alloc()`, then go into `mdb -k` and run `<address>::walk vmem_seg | ::vmem_seg -s`. That will return a list of segments allocated on the arena and most likely the span(s) that we are allocating from. ------------------------------------------ illumos-discuss Archives: https://illumos.topicbox.com/groups/discuss/discussions/T1f149f6156a80f52-Mc66b6a5526301dea8799ff8d Powered by Topicbox: https://topicbox.com
