Hi, The last few days I've had a horrible memory leak on Rawhide. The problem is: I can't find out what's causing it. According to 'top' there aren't any userspace processes which are using lots of memory, but according to 'slabtop' there is 'kmalloc-32' which is using excessive amounts of memory. This looks like something in the kernel to me. Killing services or the whole X server don't help in getting the memory released. The strange thing is I'm having this leak on 2 individual computers with completely different hardware (one is a desktop, the other is a notebook). This leak makes my systems unusable after some time (due to all userspace processes being put in the swap). The leak itself seems to be dependent on the user activity. If I leave the computer mostly idle (just Evolution and X-Chat running in the background) the leak isn't as bad as when there's lots a activity. If I play a game (using wine) for example, I need to reboot after a few hours because there's no memory left for userspace processes (everything is being swapped). Is there anybody else here who is also encountering this strange leak? Of does anybody have an idea how to make a proper diagnosis about this problem? My desktop is an Pentium 4 2.4Ghz with 1GB ram $ lspci 00:00.0 Host bridge: Intel Corporation 82845 845 [Brookdale] Chipset Host Bridge (rev 11) 00:01.0 PCI bridge: Intel Corporation 82845 845 [Brookdale] Chipset AGP Bridge (rev 11) 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 01) 01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7800 GS] (rev a2) 02:03.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 02) 02:03.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 02) 02:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Before blaming the propetiary nVidia drivers, only my notebook uses those, so the problem probably isn't in those drivers. I've tried several different Rawhide kernels (from 2.6.27-0.208.rc1.git2 to the latest of today) but they all have the same problem. I've managed to save the output of slaptop and the contents of /proc/slabinfo when the memory usage was horrible again. Maybe someone can find some useful information in them. They are published at http://ftd4linux.nl/contrib/slabtop and http://ftd4linux.nl/contrib/slabinfo Kind regards, Erik van Pienbroek -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
