I've compiled the kernel without SMP. Now the system runs fine for about 1 Week. After than, it oftens "crashes". "crashes" is not realy the thing ... diffrent things happen : * The whole system hangs WIHTOUT any kernel-message on the screen or in the logfiles, i still can ping the system * A lot of processes dieing, system is pingable, reboot with ctrl-alt-del works * All processes are in state "Z", login is still possible and so on ... After the reboot, e2fsck needs to fix a lot of things (ext2 issue...). The system is running on 2.4.4-ac18 lspci says : 00:00.0 Host bridge: Intel Corporation 440BX/ZX - 82443BX/ZX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corporation 440BX/ZX - 82443BX/ZX AGP bridge (rev 03) 00:04.0 ISA bridge: Intel Corporation 82371AB PIIX4 ISA (rev 02) 00:04.1 IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01) 00:04.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) 00:04.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 02) 00:06.0 SCSI storage controller: Adaptec AHA-2940U2/W / 7890 00:0a.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) 00:0b.0 Ethernet controller: 3Com Corporation 3c905C-TX [Fast Etherlink] (rev 74) 01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 RL The main use of the box is to serve webpages with apache+php, ftp and ssh, not too busy (load is about 0.1<->1). Ide drives are absent. Whats happending to this box? I've never had such problems. Is it because of the Dual-Board and the non-smp kernel? (i need to know this, because we can't tolerate any more downtime right now) Thanks, Thomas
