During this time I see the network load go up (output of 'netstat -w 5' and 'vmstat -w 5' attached), which I assume it's because it does heavy i/o from ~/.pan/ (NFS mounted). This doesn't happen if the system is under high cpu load, and neither does the cpu load go up when it happens. Given it's a fast machine and that pan uses at least 4 threads, I wouldn't expect that one program waiting for the network slows everything down. Is there anything I might have misconfigured? What else should I look at to find out what's happening? tks -- pica --pWyiEgJYm5f9v55/ Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="netstat-i5.out" input (Total) output packets errs bytes packets errs bytes colls 14 0 2252 14 0 2412 0 6 0 972 6 0 1020 0 4 0 648 4 0 680 0 3 0 486 3 0 510 0 7 0 1158 7 0 1214 0 7 0 1042 7 0 1114 0 51 0 5282 51 0 6266 0 3 0 486 3 0 510 0 3 0 486 3 0 510 0 11 0 1774 11 0 1886 0 11 0 1750 11 0 1934 0 1124 0 1454225 298 0 57734 0 4339 0 5672230 1057 0 188616 0 4222 0 5718896 891 0 156866 0 4119 0 5713968 782 0 142022 0 1070 0 1409540 604 0 601633 0 310 0 62440 2674 0 3795940 0 293 0 59298 2334 0 3294460 0 503 0 109436 3410 0 4740849 0 360 0 90464 2534 0 3510504 0 input (Total) output packets errs bytes packets errs bytes colls 486 0 93290 2887 0 3920730 0 494 0 110604 3009 0 4133536 0 286 0 57404 2320 0 3262816 0 223 0 45536 1190 0 1568384 0 0 0 0 0 0 0 0 6 0 972 6 0 1020 0 3 0 486 3 0 510 0 3 0 486 3 0 510 0 96 0 27776 57 0 4634 0 122 0 37352 82 0 7824 0 49 0 9330 28 0 2320 0 4 0 546 3 0 510 0 3 0 486 3 0 510 0 7 0 1134 7 0 1190 0 34 0 12756 24 0 2376 0 15 0 2324 18 0 1907 0 --pWyiEgJYm5f9v55/ Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="vmstat-w5.out" procs memory page disks faults cpu r b w avm fre flt re pi po fr sr ad0 ad2 in sy cs us sy id 0 3 0 687424 23524 173 0 0 0 165 22 0 0 382 0 701 3 1 96 0 3 0 684448 25048 63 0 0 0 132 0 0 0 456 0 2175 5 2 92 0 3 0 685572 24864 20 0 0 0 12 0 0 1 341 0 815 2 2 96 0 3 0 685572 24864 0 0 0 0 0 0 0 0 339 0 532 1 1 98 0 3 0 686680 24704 20 0 0 0 12 0 0 1 340 0 582 2 2 97 0 3 0 686712 24672 25 0 0 0 24 0 0 1 365 0 636 2 1 97 0 3 1 687820 24512 16 0 0 0 9 0 0 1 341 0 721 2 1 97 1 3 1 687820 24508 179 0 0 0 162 0 0 0 362 0 540 1 2 97 0 3 0 688924 24344 20 0 0 0 7 0 0 1 342 0 906 2 2 96 0 3 0 688928 24340 4 0 0 0 4 0 0 0 374 0 743 3 2 95 0 3 0 688928 24340 3 0 0 0 3 0 0 2 395 0 813 2 2 96 0 3 0 688928 24340 88 0 0 0 88 0 0 0 443 0 2257 5 3 92 0 4 0 688928 40936 103 0 0 0 1026 0 0 3 1116 0 4204 7 4 89 0 5 0 691184 33688 652 0 0 0 371 0 0 0 2369 0 8276 13 7 80 0 4 1 692276 28512 220 0 0 0 124 0 0 1 2200 0 6755 7 7 87 0 4 0 690956 23200 553 0 0 0 316 0 0 0 2262 0 8075 13 8 79 0 4 0 696272 31672 590 7 10 0 780 738 0 16 859 0 3410 27 4 68 0 6 0 692240 30272 110 1 1 0 141 0 0 10 1073 0 4432 4 5 91 procs memory page disks faults cpu r b w avm fre flt re pi po fr sr ad0 ad2 in sy cs us sy id 0 5 1 692240 28040 24 0 0 0 39 0 0 2 967 0 3654 3 5 93 0 6 0 692240 24896 3 0 0 0 159 0 0 10 1214 0 5034 2 5 92 0 4 0 692240 23072 32 1 1 0 137 0 0 2 982 0 3609 3 4 93 0 5 0 692372 19976 26 0 0 0 154 0 0 2 1090 0 4276 1 5 94 0 4 1 692500 29840 7 0 0 1 137 4300 0 1 1089 0 4096 1 5 94 0 4 0 692500 27784 1 0 0 0 103 0 0 2 887 0 2923 0 4 96 0 3 0 692500 27468 0 0 0 0 16 0 0 0 584 0 1730 3 2 95 0 3 0 692500 27468 0 0 0 0 0 0 0 0 331 0 363 0 1 99 0 3 1 692500 27468 0 0 0 0 0 0 0 1 332 0 368 0 1 99 0 3 0 692500 27468 0 0 0 0 0 0 0 0 331 0 366 0 1 99 0 3 0 692500 27468 0 0 0 0 0 0 0 0 331 0 361 0 1 98 0 3 0 692500 27464 0 0 0 0 0 0 0 0 386 0 584 0 2 98 1 3 0 692500 27464 1 0 0 0 0 0 0 0 393 0 689 0 1 98 0 3 0 692500 27464 1 0 0 0 0 0 0 0 355 0 443 0 1 99 0 3 0 692500 27464 0 0 0 0 1 0 0 0 332 0 355 0 1 99 0 3 0 692500 27464 0 0 0 0 0 0 0 1 335 0 356 0 1 99 1 3 0 692500 27464 0 0 0 0 0 0 0 0 331 0 331 0 1 99 0 3 1 692500 27464 0 0 0 0 1 0 0 2 354 0 535 0 2 98 procs memory page disks faults cpu r b w avm fre flt re pi po fr sr ad0 ad2 in sy cs us sy id 1 3 0 689648 28456 37 0 0 0 76 0 0 0 696 0 2226 6 3 92 --pWyiEgJYm5f9v55/--
