Everything goes fine, notable perfomance increase occures, but the problem is I'm really often touch the following problem: __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. __alloc_pages: 1-order allocation failed. This message may also show 1-order, 0-order, 3-order failures (only one type at the time). This problems also appeared then I tried to use 2.4.1-2.4.3 kernels. This sometimes leads to system hang, sometimes some processes gets unkillable (even by kill -9) and in some cases I do not see any bad results from this, but still this does not looks the right thing to happen. The problem is the systems this happens on are not short of memory. Here is the free output for the system I had this happened this morning: rat:~ # free total used free shared buffers cached Mem: 1028628 1025820 2808 0 9340 332412 -/+ buffers/cache: 684068 344560 Swap: 2097136 0 2097136 Does anyone has any ideas about this problem ? -- Best regards, Peter mailto:pz@spylog.ru
