Monitoring, Management & Location Tracking

If "service support_connection start" fails with the following error message or similar:

FATAL: Could not load /lib/modules/2.6.18-194.32.1.el5/modules.dep: No such file or directory

This usually indicates that a kernel upgrade has been performed but the required server reboot has not happened yet.

You can verify the current RUNNING kernel with "uname -a"

[root@garrison modules]# uname -a
Linux garrison.corp.airwave.com 2.6.18-274.7.1.el5 #1 SMP Thu Oct 20 16:21:01 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

If you do an ls -l of the /lib/modules you should entries for the current kernel and possibly for older kernels.

[root@garrison modules]# ls -l /lib/modules/
total 12
drwxr-xr-x 3 root root 4096 Oct 24 06:18 2.6.18-238.12.1.el5/
drwxr-xr-x 6 root root 4096 Nov 21 15:36 2.6.18-274.7.1.el5/

You can check the current INSTALLED kernel via "rpm -qa kernel"

[root@garrison modules]# rpm -qa kernel
kernel-2.6.18-274.7.1.el5.x86_64

if the current RUNNING kernel from "uname -a" doesn't match the INSTALLED kernel "rpm -qa kernel" and you can see that the FATAL error is referencing an older or missing kernel modules.dep then a reboot will probably resolve the issue.
