Our SLES 8 for AMD64 application server crashed today. I had to have our colocation facility do a hard reboot - but at least it seems to have come up OK. I looked in /var/log/messages and, but not much in the way of explanation was found: May 27 09:47:49 kingfish saslauthd[12031]: pam_mysql: acct_mgmt called but not implemented. Dont panic though :) May 27 09:47:49 kingfish pop3d[26193]: login: ip68-109-128-18.ph.ph.cox.net[68.109.128.18] lee.fromltoj.com plaintext+TLS May 27 09:48:49 kingfish master[1502]: process 26193 exited, status 0 May 27 09:49:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 27 09:49:00 kingfish /USR/SBIN/CRON[26195]: (root) CMD ( rm -f /var/spool/cron/lastrun/cron.hourly) May 27 10:00:09 kingfish syslogd 1.4.1: restart. May 27 10:00:10 kingfish /etc/hotplug/usb.rc[451]: loaded HCD: usb-ohci Any ideas are appreciated on the cause. I did research further back and sometime after May 19th I started to get the message "Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep". It happens like 300 to 400 times per day. I believe that around that time I applied a kernel security patch for AMD64: Title: Security update for Linux kernel (AMD64) http://sdb.suse.de/en/psdb/html/665565dbb2c37d261e5eaa9fd51c857e.html _______________________________________________________ Applies to Product(s): SuSE Linux Enterprise Server 8 for AMD64 UnitedLinux 1.0 Package: k_deflt,k_numa,k_smp,kernel-source Release: 20040429 Obsoletes: none Here is the output from "uname -a" and a snippet from the logs, with some lines before and after the 'dependency' error: kingfish:/var/log # uname -a Linux kingfish 2.4.21-215-smp #1 SMP Tue Apr 27 16:05:19 UTC 2004 x86_64 unknown May 20 23:55:42 kingfish ctl_cyrusdb[29242]: checkpointing cyrus databases May 20 23:55:42 kingfish ctl_cyrusdb[29242]: archiving database file: /var/lib/imap/mailboxes.db May 20 23:55:42 kingfish ctl_cyrusdb[29242]: archiving log file: /var/lib/imap/db/log.0000000002 May 20 23:55:42 kingfish ctl_cyrusdb[29242]: done checkpointing cyrus databases May 20 23:55:42 kingfish master[1502]: process 29242 exited, status 0 May 20 23:59:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 20 23:59:00 kingfish /USR/SBIN/CRON[29245]: (root) CMD ( rm -f /var/spool/cron/lastrun/cron.hourly) May 21 00:00:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 21 00:00:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 21 00:00:00 kingfish /USR/SBIN/CRON[29251]: (root) CMD ( /usr/lib64/sa/sa2 -A #update reports every 6 hour) May 21 00:00:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 21 00:00:00 kingfish /USR/SBIN/CRON[29254]: (root) CMD ( /usr/lib64/sa/sa1 ) May 21 00:00:00 kingfish modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.19-SMP/modules.dep (No such file or directory) May 21 00:00:00 kingfish /USR/SBIN/CRON[29257]: (root) CMD ( test -x /usr/lib/secchk/security-control.sh && /usr/lib/secchk/security-control.sh daily &) May 21 00:00:01 kingfish master[29683]: about to exec /usr/lib/cyrus/bin/lmtpd Thank you in advance - Richard
