Hello. On our FreeBSD 4.6.1-10 NFS fileserver, I traced back using tcpdump what happens when a SunOS (5.7, 5.8) client access the shares, because heavy file operations (as `tar xf archive.tar') make the server slow down a lot, for all NFS clients (Linux and SunOS) of the network. Here is a sample; pave is the freebsd server, cougourde a SunOS client: 12:38:19.106909 cougourde.1896274845 > pave.imag.fr.nfs: 156 read [|nfs] (DF) 12:38:19.106919 pave.imag.fr.nfsd > cougourde.829: . ack 7446920 win 1704 (DF) 12:38:19.106958 pave.imag.fr.nfs > cougourde.1896274841: reply ok 1460 read (DF) 12:38:19.106970 pave.imag.fr.nfs > cougourde.1402747809: reply ERR 1460 (DF) 12:38:19.106984 pave.imag.fr.nfs > cougourde.1459477691: reply ERR 1460 (DF) 12:38:19.107002 pave.imag.fr.nfs > cougourde.3219763278: reply ERR 1460 (DF) 12:38:19.107019 pave.imag.fr.nfs > cougourde.4279864393: reply ERR 1460 (DF) 12:38:19.107034 cougourde.1896274846 > pave.imag.fr.nfs: 1460 write [|nfs] (DF) 12:38:19.107045 pave.imag.fr.nfs > cougourde.516137457: reply ERR 1460 (DF) 12:38:19.107458 cougourde.829 > pave.imag.fr.nfsd: . ack 1328209 win 8760 (DF) 12:38:19.107491 pave.imag.fr.nfs > cougourde.3243966567: reply ERR 1460 (DF) 12:38:19.107506 pave.imag.fr.nfs > cougourde.299317409: reply ERR 1460 (DF) 12:38:19.107706 cougourde.829 > pave.imag.fr.nfsd: . ack 1331129 win 8760 (DF) 12:38:19.107727 pave.imag.fr.nfs > cougourde.3910987679: reply ERR 1460 (DF) 12:38:19.107763 pave.imag.fr.nfs > cougourde.3831861125: reply ERR 1460 (DF) 12:38:19.107951 cougourde.829 > pave.imag.fr.nfsd: . ack 1334049 win 8760 (DF) 12:38:19.107970 pave.imag.fr.nfs > cougourde.2686040787: reply ERR 1460 (DF) 12:38:19.107988 pave.imag.fr.nfs > cougourde.423492228: reply ERR 1460 (DF) 12:38:19.108198 cougourde.829 > pave.imag.fr.nfsd: . ack 1336969 win 8760 (DF) 12:38:19.108218 pave.imag.fr.nfs > cougourde.351486713: reply ERR 1460 (DF) 12:38:19.108236 pave.imag.fr.nfs > cougourde.2373543498: reply ERR 1460 (DF) 12:38:19.108442 cougourde.829 > pave.imag.fr.nfsd: . ack 1339889 win 8760 (DF) 12:38:19.108461 pave.imag.fr.nfs > cougourde.3607419678: reply ERR 1460 (DF) 12:38:19.108480 pave.imag.fr.nfs > cougourde.463905628: reply ERR 1460 (DF) 12:38:19.108696 cougourde.829 > pave.imag.fr.nfsd: . ack 1342809 win 8760 (DF) 12:38:19.108717 pave.imag.fr.nfs > cougourde.2733721915: reply ERR 1460 (DF) 12:38:19.108730 pave.imag.fr.nfs > cougourde.2641096502: reply ERR 1460 (DF) 12:38:19.108935 cougourde.829 > pave.imag.fr.nfsd: . ack 1345729 win 8760 (DF) 12:38:19.108953 pave.imag.fr.nfs > cougourde.2777313359: reply ERR 1460 (DF) 12:38:19.108974 pave.imag.fr.nfs > cougourde.1182848957: reply ERR 1460 (DF) 12:38:19.109170 cougourde.829 > pave.imag.fr.nfsd: . ack 1348649 win 8760 (DF) 12:38:19.109190 pave.imag.fr.nfs > cougourde.1731922451: reply ERR 1460 (DF) 12:38:19.109203 pave.imag.fr.nfs > cougourde.3709459188: reply ERR 1460 (DF) 12:38:19.109416 cougourde.829 > pave.imag.fr.nfsd: . ack 1351569 win 8760 (DF) 12:38:19.109659 cougourde.829 > pave.imag.fr.nfsd: . ack 1354489 win 8760 (DF) 12:38:19.109906 cougourde.829 > pave.imag.fr.nfsd: . ack 1357409 win 8760 (DF) 12:38:19.109922 pave.imag.fr.nfs > cougourde.1285920604: reply ERR 780 (DF) 12:38:19.207379 cougourde.829 > pave.imag.fr.nfsd: . ack 1358189 win 8760 (DF) 12:38:19.207410 pave.imag.fr.nfs > cougourde.1896274843: reply ok 1460 read (DF) 12:38:19.207421 pave.imag.fr.nfs > cougourde.3031018447: reply ERR 1460 (DF) 12:38:19.207432 pave.imag.fr.nfs > cougourde.20880209: reply ERR 1460 (DF) 12:38:19.207449 pave.imag.fr.nfs > cougourde.568366832: reply ERR 1460 (DF) 12:38:19.207466 pave.imag.fr.nfs > cougourde.3207344769: reply ERR 1460 (DF) 12:38:19.207478 pave.imag.fr.nfs > cougourde.1336428539: reply ERR 1460 (DF) 12:38:19.207503 pave.imag.fr.nfsd > cougourde.829: . ack 7448536 win 33176 (DF) 12:38:19.207903 cougourde.829 > pave.imag.fr.nfsd: . ack 1361109 win 8760 (DF) 12:38:19.207937 pave.imag.fr.nfs > cougourde.2728028655: reply ERR 1460 (DF) 12:38:19.207952 pave.imag.fr.nfs > cougourde.2548942410: reply ERR 1460 (DF) 12:38:19.208154 cougourde.829 > pave.imag.fr.nfsd: . ack 1364029 win 8760 (DF) 12:38:19.208182 pave.imag.fr.nfs > cougourde.2415153561: reply ERR 1460 (DF) 12:38:19.208199 pave.imag.fr.nfs > cougourde.956695624: reply ERR 1460 (DF) 12:38:19.208388 cougourde.829 > pave.imag.fr.nfsd: . ack 1366949 win 8760 (DF) 12:38:19.208408 pave.imag.fr.nfs > cougourde.2914024654: reply ERR 1460 (DF) 12:38:19.208421 pave.imag.fr.nfs > cougourde.4161581036: reply ERR 1460 (DF) 12:38:19.208711 cougourde.3653305676 > pave.imag.fr.nfs: 1460 proc-2638411474 (DF) 12:38:19.208833 cougourde.3952195429 > pave.imag.fr.nfs: 1460 proc-715245293 (DF) 12:38:19.208853 pave.imag.fr.nfsd > cougourde.829: . ack 7451456 win 33176 (DF) 12:38:19.208957 cougourde.626786551 > pave.imag.fr.nfs: 1460 proc-3016571487 (DF) There must be something wrong in my setup (see all these 'ERR' lines), but I do not know what.
