It always happens afer some time of having some load on the system (I'm building ports with tinderbox and during the build process it just hangs up). The system does nothing write out on the console, neither the CRT, nor the serial console. The system itself is: CPU: Intel Pentium III (845.64-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x683 Stepping = 3 Features=0x387fbff real memory = 805240832 (767 MB) avail memory = 778481664 (742 MB) ACPI APIC Table: FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 1 cpu1 (AP): APIC ID: 0 ioapic0 irqs 0-23 on motherboard while the diskspace is provided by an 3ware RAID: twa0: <3ware 9000 series Storage Controller> port 0x2400-0x24ff mem 0xf4101000-0xf41010ff,0xf4800000-0xf4ffffff irq 18 at device 11.0 on pci0 twa0: INFO: (0x04: 0x0053): Battery capacity test is overdue: twa0: INFO: (0x15: 0x1300): Controller details:: Model 9500S-4LP, 4 ports, Firmware FE9X 2.08.00.009, BIOS BE9X 2.03.01.052 da0 at twa0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-3 device da0: 100.000MB/s transfers da0: 715224MB (1464778752 512 byte sectors: 255H 63S/T 91178C) I had - in the past - sometimes messages left which where indicating, that the system was not able to allocate swap space fast enough if I recall it correctly (_not_ out of swap space!) but the RAID is kinda fast imho. Any idea what I could do to shed some more light on this behaviour? Why it is happening and what really is causing it? Would enabling the kernel debugger really help here? I mean the system is really hanging up - except ping response it is not responding to anything except the reset switch ;) Greetings, Oliver -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
