This is still present in head at r343598. I have a 2GB Rock64 connected to my NFS server via GigE. By default it has 42025 mbuf clusters (this is much lower than x86 systems with equivalent RAM) that I've increased to 200000. Running a "make -j4 buildworld" and sampling "vmstat -z" every minute, I get the following (this is restarting a failed buildworld using META_MODE). Note that it's not a gradual leak but seems to leak a chunk of clusters and then sits at that level for several minutes. Stopping the buildworld doesn't free up the clusters so they are leaked, not just in use. The following isn't perfectly monotonic but only goes backwards at one point. 0755:mbuf_cluster: 2048, 200000, 3542, 506, 3687, 0, 0 0756:mbuf_cluster: 2048, 200000, 4554, 1012, 4725, 0, 0 0757:mbuf_cluster: 2048, 200000, 4554, 1012, 4748, 0, 0 0758:mbuf_cluster: 2048, 200000, 4554, 1012, 4771, 0, 0 0759:mbuf_cluster: 2048, 200000, 4554, 1012, 4794, 0, 0 0800:mbuf_cluster: 2048, 200000, 10120, 760, 20290, 0, 0 0801:mbuf_cluster: 2048, 200000, 10879, 1265, 24025, 0, 0 0802:mbuf_cluster: 2048, 200000, 10879, 1265, 25314, 0, 0 0803:mbuf_cluster: 2048, 200000, 11132, 1012, 25690, 0, 0 0804:mbuf_cluster: 2048, 200000, 12144, 1012, 30254, 0, 0 0805:mbuf_cluster: 2048, 200000, 13915, 1013, 50187, 0, 0 0806:mbuf_cluster: 2048, 200000, 19734, 760, 72872, 0, 0 0807:mbuf_cluster: 2048, 200000, 20746, 1012, 92112, 0, 0 0808:mbuf_cluster: 2048, 200000, 20746, 1012, 92254, 0, 0 0809:mbuf_cluster: 2048, 200000, 21252, 1012, 93880, 0, 0 0810:mbuf_cluster: 2048, 200000, 23023, 1013, 97112, 0, 0 0811:mbuf_cluster: 2048, 200000, 31625, 1013, 124799, 0, 0 0812:mbuf_cluster: 2048, 200000, 31625, 1013, 124858, 0, 0 0813:mbuf_cluster: 2048, 200000, 31625, 1013, 124969, 0, 0 0814:mbuf_cluster: 2048, 200000, 31625, 1013, 125382, 0, 0 0815:mbuf_cluster: 2048, 200000, 31625, 1013, 125451, 0, 0 0816:mbuf_cluster: 2048, 200000, 40820, 1498, 220253, 0, 0 0817:mbuf_cluster: 2048, 200000, 48829, 1441, 300628, 0, 0 0818:mbuf_cluster: 2048, 200000, 48829, 1441, 303776, 0, 0 0819:mbuf_cluster: 2048, 200000, 48829, 1441, 309853, 0, 0 0820:mbuf_cluster: 2048, 200000, 49335, 1185, 316688, 0, 0 0821:mbuf_cluster: 2048, 200000, 50094, 1180, 323880, 0, 0 0822:mbuf_cluster: 2048, 200000, 50094, 1430, 326295, 0, 0 0823:mbuf_cluster: 2048, 200000, 51106, 920, 332130, 0, 0 0824:mbuf_cluster: 2048, 200000, 51106, 1172, 334384, 0, 0 0825:mbuf_cluster: 2048, 200000, 51106, 1422, 336230, 0, 0 0826:mbuf_cluster: 2048, 200000, 51106, 1422, 339243, 0, 0 0827:mbuf_cluster: 2048, 200000, 50656, 1873, 342646, 0, 0 0828:mbuf_cluster: 2048, 200000, 50853, 1603, 351059, 0, 0 0829:mbuf_cluster: 2048, 200000, 51106, 1198, 352932, 0, 0 0830:mbuf_cluster: 2048, 200000, 52118, 2112, 365459, 0, 0 0831:mbuf_cluster: 2048, 200000, 52118, 1936, 366591, 0, 0 0832:mbuf_cluster: 2048, 200000, 52118, 1838, 367848, 0, 0 0833:mbuf_cluster: 2048, 200000, 54142, 1658, 383418, 0, 0 0834:mbuf_cluster: 2048, 200000, 54142, 1658, 385541, 0, 0 0835:mbuf_cluster: 2048, 200000, 54901, 1137, 392943, 0, 0 0836:mbuf_cluster: 2048, 200000, 55407, 1583, 403383, 0, 0 0837:mbuf_cluster: 2048, 200000, 55407, 1583, 411514, 0, 0 0838:mbuf_cluster: 2048, 200000, 55913, 1553, 420834, 0, 0 0839:mbuf_cluster: 2048, 200000, 55913, 1553, 424251, 0, 0 0840:mbuf_cluster: 2048, 200000, 56166, 1300, 428153, 0, 0 0841:mbuf_cluster: 2048, 200000, 56166, 1300, 429588, 0, 0 0842:mbuf_cluster: 2048, 200000, 56166, 1300, 431134, 0, 0 0843:mbuf_cluster: 2048, 200000, 56166, 1538, 433335, 0, 0 0844:mbuf_cluster: 2048, 200000, 56419, 1285, 435480, 0, 0 0845:mbuf_cluster: 2048, 200000, 57431, 1463, 440081, 0, 0 0846:mbuf_cluster: 2048, 200000, 57431, 1463, 441174, 0, 0 0847:mbuf_cluster: 2048, 200000, 57684, 1448, 449174, 0, 0 0848:mbuf_cluster: 2048, 200000, 57684, 1448, 450645, 0, 0 0849:mbuf_cluster: 2048, 200000, 58190, 1180, 460372, 0, 0 0850:mbuf_cluster: 2048, 200000, 58190, 1418, 462094, 0, 0 0851:mbuf_cluster: 2048, 200000, 59708, 1090, 468385, 0, 0 0852:mbuf_cluster: 2048, 200000, 59708, 1568, 470372, 0, 0 0853:mbuf_cluster: 2048, 200000, 59708, 1568, 472798, 0, 0 0854:mbuf_cluster: 2048, 200000, 60720, 1272, 480909, 0, 0 0855:mbuf_cluster: 2048, 200000, 60720, 1512, 484643, 0, 0 |
