FreeBSD fileserver1.smartrafficenter.net 4.7-STABLE FreeBSD 4.7-STABLE #0: Mon Dec 16 19:41:03 EST 2002 toor at fileserver1.smartrafficenter.net:/usr/obj/usr/src/sys/FILESERVER1 i386
Running 4.7 stable with sources CVSed on 16 Dec 2002.
My fileserver has been running since 17 Dec 2002 and suddenly lost its
ability to talk on the network today. Went to the console to discover
a flood of messages that it was out of mbuf clusters, read tuning(7)
for more info.
I immediately ran netstat -m and saw indeed there were 6656 mbuf
clusters allocated, 6656 used, and 6656 peak. A number of requests
for memory were being denied at this point. While browsing the tuning(7)
man page for where and how to increase this number, the kernel panicked.
The computer is a Dell PowerEdge 1650 with two 1.4 GHz P-III processors
and 1 GB RAM. Output of dmesg and gdb on debug kernel and core file is
provided below. Kernel config file is attached.
What can I do to help solve any problems that might exist in the kernel
code, and what suggestions do you have to keep this from happening on
my fileserver again?
Kernel, debug kernel, CVS date, kernel config, and core file can be
made available upon request.
Thanks much,
Kevin A. Pieckiel
