I'm using the FreeBSD 5.2(FreeBSD 5.2-RELEASE #0: Sun Jan 11 04:21:45 GMT 2004),default installation, to collect packets with TCPDUMP. The computer has:
-> CPU: AMD Athlon(tm) XP 2400+ (2004.56-MHz 686-class CPU)
-> real memory = 536805376 (511 MB)
-> rl0: <RealTek 8139 10/100BaseTX> port 0xd400-0xd4ff mem 0xdfffbf00-0xdfffbfff irq 18 at device 8.0 on pci0, etc.
The problem is when I start the program TCPDUMP to collect the packets from a 32Mb/s link (at the rl0 interface). After some time, the following log error messages appear:
"Mar 30 11:29:22 p2p kernel: panic: vm_fault: fault on nofault entry, addr: e0aae000

What can I do to correct this problem?
Thanks in advance.
