Hello Doug, Tuesday, March 1, 2005, 6:59:42 PM, you wrote: > Some more exploration is necessary. Can you make the crashdump and debug > kernel available? Also, what was running when this panic tripped? ("info > threads" in kgdb may be useful.) This crash occured while doing backup on a live system (snapshot was enabled to get consistent backup). But it might not be related to the snapshot, today (Tuesday) I noticed on morning that system crashed again. I posted information about that before (Message-ID: <596413574.20050301104045_at_takeda.tk>). This crash also occured in same line in the code, but the difference is that it happened when I wasn't around. So it's hard to me to tell if the line is just coincidence, or the crashes are related. From the logfile (of the second crash (not this one)): [...] Mar 1 07:18:32 chinatsu httpd: PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 240 bytes) in /usr/local/www/phpwiki-1.3.10/lib/WikiUserNew.php on line 1012 Mar 1 09:59:26 chinatsu syslogd: restart Mar 1 09:59:26 chinatsu syslogd: kernel boot file is /boot/kernel/kernel [...] Looks like it happened somewhere after 7:18:32 (9:59:26 was when I went to the console and asked to dump core file) I showed the log file, because the message is strange. Maybe is related to the crash. Please note that this is from the second crash that occured today, not the one we're analyzing currently. As for the list of threads from the first core dump, here it goes: (kgdb) info threads 149 TID 100050 sched_switch (td=0xc1695000, newtd=0xc14e04b0, flags=1) at /usr/src/sys/kern/sched_4bsd.c:866 148 TID 100254 sched_switch (td=0xc2d9a640, newtd=0xc14e3e10, flags=1) at /usr/src/sys/kern/sched_4bsd.c:866 147 TID 100176 sched_switch (td=0xc1d0b960, newtd=0xc211e000, flags=1) at /usr/src/sys/kern/sched_4bsd.c:866 146 TID 100219 sched_switch (td=0xc1f9ae10, newtd=0xc14e04b0, flags=1) at /usr/src/sys/kern/sched_4bsd.c:866 kgdb: kvm_read: invalid address (d1791da0) 145 TID 100262 0x00000000 in ??

I belive there is a lot of sensitive data (besides that is a core dump of a kernel, the crash occured while doing a backup). The worst thing is that it's not only my data but also data of my users. Isn't there a better way? -- Best regards, Dariusz mailto:d.kulinski_at_gmail.com http://www.takeda.tkReceived on Wed Mar 02 2005 - 04:29:40 UTC
