While fixing sk(4) driver issues I'm seeing these mbuf cluster
leaks on sparc64/i386. Both machines are SMP.
sparc64(sk(4))
386/1946/2332 mbufs in use (current/cache/total)
1710/290/2000/2000 mbuf clusters in use (current/cache/total/max)
^^^^^^^^^^^^^^^^^^
0/5/4528 sfbufs in use (current/peak/max)
3516K/1066K/4583K bytes allocated to network (current/cache/total)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines
i386(em(4))
388/1929/2317 mbufs in use (current/cache/total)
1727/273/2000/2000 mbuf clusters in use (current/cache/total/max)
^^^^^^^^^^^^^^^^^^
0/7/3504 sfbufs in use (current/peak/max)
3551K/1028K/4579K bytes allocated to network (current/cache/total)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines
Related information from vm.zone:
mbuf_ext_ref: 4, 0, 0, 0, 0
mbuf_jumbo_1: 16384, 0, 0, 0, 0
mbuf_jumbo_9: 9216, 0, 0, 0, 0
mbuf_jumbo_4: 4096, 0, 0, 0, 0
mbuf_cluster: 2048, 2000, 2000, 0, 2000
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
mbuf: 256, 0, 788, 1657, 87811655
mbuf_packet: 256, 0, 2160, 285, 50505646
To confirm the mbuf leak I lowered the cluter limit. netperf is
blocked on a "zonelimit".
Any ideas?
