Debugging crash


I'm using Ubuntu 10.04. I've noticed my server has crashed twice in the past couple days.

From what I've gathered I should look at /var/log/messages for more info on crashes, but mine only has a bunch of restart logs for a date that doesn't make any sense (the server has only been up two weeks):
Code:
Apr 11 05:37:07 test1 syslogd 1.5.0#5ubuntu4: restart. Apr 25 01:07:36 test1 syslogd 1.5.0#5ubuntu4: restart. Apr 25 01:07:39 test2 syslogd 1.5.0#5ubuntu4: restart.
I also did "last -x" which at least let me know the culprit was ppp:

Code:
router ppp0 [ip.ad.dr.ess] Sat Mar 30 06:52 - 06:54 (00:01) runlevel (to lvl 2) 2.6.32-042stab07 Sat Mar 30 06:52 - 06:55 (00:02) reboot system boot 2.6.32-042stab07 Sat Mar 30 06:52 - 06:55 (00:02) router ppp1 [ip.ad.dr.ess] Sat Mar 30 04:13 - crash (02:39) router ppp0 [ip.ad.dr.ess] Fri Mar 29 23:13 - 04:13 (05:00) router ppp0 [ip.ad.dr.ess] Fri Mar 29 23:10 - 23:12 (00:01) router ppp1 [ip.ad.dr.ess] Fri Mar 29 23:06 - 23:12 (00:05) router ppp0 [ip.ad.dr.ess] Fri Mar 29 13:37 - 23:08 (09:31) router ppp1 [ip.ad.dr.ess] Fri Mar 29 10:12 - 13:39 (03:26) router ppp0 [ip.ad.dr.ess] Fri Mar 29 08:22 - 10:14 (01:52) router ppp1 [ip.ad.dr.ess] Fri Mar 29 04:45 - 08:23 (03:38) router ppp0 [ip.ad.dr.ess] Fri Mar 29 00:10 - 04:47 (04:36) anthony ppp0 [ip.ad.dr.ess] Thu Mar 28 16:14 - 17:12 (00:57) router ppp1 [ip.ad.dr.ess] Thu Mar 28 16:01 - 00:12 (08:11) router ppp0 [ip.ad.dr.ess] Thu Mar 28 11:16 - 16:03 (04:46) router ppp0 [ip.ad.dr.ess] Thu Mar 28 11:15 - 11:16 (00:01) runlevel (to lvl 2) 2.6.32-042stab07 Thu Mar 28 11:15 - 06:52 (1+19:37) reboot system boot 2.6.32-042stab07 Thu Mar 28 11:15 - 06:55 (1+19:40) router ppp0 [ip.ad.dr.ess] Thu Mar 28 10:08 - crash (01:06)
Where can I get a decent log for this or how can I set it up to log on the next crash. Thanks!

There's the @reboot alias for cron. See man 5 cron. You could write a script which gathers system info upon reboot in addition to telling you it happened.
