Hartmann >Release: FreeBSD 5.3-RC1 i386 >Organization: Department of Geophysics, Johannes Gutenberg-Universitaet Mainz >Environment: System: FreeBSD edda.physik.uni-mainz.de 5.3-RC1 FreeBSD 5.3-RC1 #26: Sun Oct 17 10:48:55 UTC 2004 root@edda.physik.uni-mainz.de:/usr/obj/usr/src/sys/EDDA i386 Mainboard: ASUS CUR-DLS, SMP, 1GB RAM, SCSI (no ATA). Kernel config like GENERIC with some extensions: using pf, ALTQ, SMP, PIM, MROUTING, disabled driver which I do not need or use. Utilizing onboard fxp0 NIC or em0 NIC (64Bit PCI, Intel GBit Server NIC). >Description: Applying queues to network connections with /etc/pf.conf via 'altq' pushes the likelyhood of crashes enormously! I recognized this on fxp0 and em0. Disabling bandwith limiting in pf-config leaves the system more stable. >How-To-Repeat: Configure pf and ALTQ, use queues in /etc/pf.conf (maybe SMP should also be used, but SMP triggers the problem more quickly). >Fix: Disable queues in pf.conf. >Release-Note: >Audit-Trail: >Unformatted:
