All of a sudden, less started to dump core (SIGSEGV). I could not even start less by itself: > less without it getting a SIGSEGV, and in fact no user could run less without getting a SIGSEGV, but it did work perfectly a few minutes earlier. This morning, I tried to run less again, and now it was working! No core dumps! How can this happen? Something overwriting the page/buffer cache? Unfortunately, I don't know how to reproduce it. I'm writing this because it was so strange that I felt I had to share it. There are no messages in the (dmesg) log. /Tobias, a little bit worried Semi-random info: 00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02) 00:07.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] (rev 01) 00:07.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] 00:07.2 USB Controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01) 00:0b.0 VGA compatible controller: ATI Technologies Inc 210888GX [Mach64 GX] (rev 01) 00:0f.0 Ethernet controller: Davicom Semiconductor, Inc.
