AFT event: system crashes now and again

AFT event: system crashes now and again

Post by Heiko Swar » Wed, 27 Mar 2002 16:54:26



Hi Experts,

HW:    E220R, 1 Sparc CPU
OS:    Solaris 7, including patch: 106541-19
The system is not under heavy usage, just one third party daemon is running.
Now and again the system crashes (every few days).
/var/adm/messages doesn't give any useful information (/etc/syslog.conf is
default)
I try to examine the crash dump but unfortunately I'm not very experienced
in analyzing dumps.
The only (may be) valuable information I could extract is:

root #crash -d ./vmcore.5
dumpfile = ./vmcore.5, namelist = /dev/ksyms, outfile = stdout

Quote:> status

system name:    SunOS
release:        5.7
node name:      galileo
version:        Generic_106541-19
machine name:   sun4u
time of crash:  Wed Mar 20 17:49:20 2002
age of system:  2 day, 9 hr., 42 min.
panicstr:       [AFT1] errID 0x0001bcf7.4cd15588 %sError(s)
    See previous message(s) for details
panic registers:
        pc: 1001063c      sp: 2a100056ac1

Is there anybody here who can help me finding the cause for these crashes?
Many thanks in advance!
Heiko

1. System crashed again, when dialing my ISP, as usual.

My system crashed again this morning when dialing my ISP. This is when
it always crashes (i.e., when it crashes, it crashes calling my ISP;
it by no means crashes every time).

My /var/log/messages had this to say:

Mar 25 06:07:01 valinux ifup-ppp: pppd started for ppp0 on /dev/modem
at 115200
Mar 25 06:07:01 valinux kernel: CSLIP: code copyright 1989 Regents of
the University of California

Mar 25 06:07:31 valinux kernel: PPP BSD Compression module registered
Mar 25 06:07:31 valinux kernel: PPP Deflate Compression module
registered

When things work, it says this instead:

Mar 25 06:38:10 valinux ifup-ppp: pppd started for ppp0 on /dev/modem
at 115200
Mar 25 06:38:10 valinux kernel: registered device ppp0

Mar 25 06:38:40 valinux pppd[1337]: local  IP address 208.225.67.131
Mar 25 06:38:40 valinux pppd[1337]: remote IP address 208.225.64.55

Am I correct in inferring that there is a bug in pppd? It does not
seem to be a simple cracker problem as tripwire does not notice that
anything is changed in the ppp area.

I have ppp-2.3.11-4 on this machine, but do not see anything newer for
Red Hat Linux 6.2 that I am running. This has kernel
kernel-2.2.14-VA.2.1smp running at the moment. This supposedly has
most of the current bugs fixed. There is a
kernel-smp-2.2.14-VA.5.1.i686.rpm out there that I have run in the
past, but when I reinstalled everything in an effort to track down
this bug, I did not install the new kernel; i.e., it had the problem
too. They also have a kernel-smp-2.2.18pre11-va2.0. I am not clear if
a pre11-va2.0 is the way to go or not. The "pre" worries me.
