This is really easy to reproduce for me, just starting a memory hog, so swap is touched, and i was unable to reproduce this behaviour on 2.4.0. also, i found this in my syslog: Feb 9 01:57:31 bakvis kernel: __alloc_pages: 3-order allocation failed. Feb 9 01:57:31 bakvis kernel: __alloc_pages: 2-order allocation failed. Feb 9 01:57:31 bakvis kernel: __alloc_pages: 3-order allocation failed. Feb 9 01:57:31 bakvis last message repeated 209 times (note 100+ such messages in the same minute) (and much more of this). i cannot exactly remember what i was doing then, but i think it was stressing the system with make -j2 or memory consuming programs like Xfree ...) i couldnot reproduce it today. here some sample vmstat output: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 1 1 0 68076 1864 4100 79204 2 198 10 109 522 1351 5 6 88 1 5 0 70056 1688 4128 79492 42 668 548 241 852 2432 19 4 76 3 2 0 69116 1544 3936 78848 20 266 309 102 340 754 16 4 80 0 5 0 68940 1468 3952 78932 4 1328 95 355 828 727 3 2 9 1 3 0 67196 1944 4044 77376 260 54 134 31 311 600 29 2 69 0 4 0 66724 1628 4064 78160 0 530 320 151 314 322 18 2 80 3 0 0 66360 1464 4072 77904 56 432 142 131 322 460 11 3 85 2 1 2 67632 1484 4072 79392 26 1076 74 306 636 399 1 2 9 2 2 0 68012 1464 4000 80108 86 1084 168 294 469 445 6 2 9 greetings, Frank Dekervel -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
