hi all...
i'm running an netbsd 6 (6.0 NetBSD 6.0 (XEN3_DOMU) amd64) instance on amazon since december last year. everything was working nicely until about 2 months ago when the system sporadically started rebooting itself. it happens once a week on average. sometimes twice. the last line in the messages log always looks like this:
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@Nov 2 07:21:55 ip-10-62-123-59 syslogd[310]: restart
it always happens right before the default daily cron (which is set for 3:15 am by default). around 3:12 am.
the only things the machine runs are httpd and mysqld..
has anybody experienced this? i would greatly appreciate any thoughts that can resolve this problem...
thanks...
