Adding David as he suggested looking at slabtop. Gr. AvS -------- Original Message -------- Subject: Re: Out of memory on 3.5 kernels Date: Fri, 21 Sep 2012 21:49:31 +0200 From: Nico Schottelius To: Arend van Spriel CC: Nico Schottelius , "linux-kernel@vger.kernel.org" , "linux-wireless@vger.kernel.org" Latest results: - it seems I can trigger the problem by doing the backup to my external usb disk - the usb disk uses jfs - jfs seems to take the major part in cache memory consumption I've attached dmesg and slabtop outputs of various stages: - before and during the backup I've had to abort the backup, because memory pressure made the system almost completly unusable. Hope this helps & someone has a clue on what went wrong were... Cheers, Nico -- PGP key: 7ED9 F7D3 6B10 81D7 0EC5 5C09 D7DC C8E4 3187 7DF0
