hey cluster gurus..
I have a 2 node cluster thats been running without issue for quite a while.. all of a sudden one of the nodes will not completely start the apache webserver service.. it looks like this
[root tf1 ~]# clustat

Service Name Owner (Last) State ------- ---- ----- ------ ----- Apache Service tf1 starting postfix service tf1 started [root tf1 ~]# and I see that the httpd is NOT started. although, if I do /etc/init.d/httpd start
the service starts without issue.

grepping for apache and http in the logs, I see this..

Im guessing its the  stop on script "cluster_apache" returned 1 (generic error)
but I looked at the /etc/init.d/httpd on tf1 and tf2 and they are both the same size

[root tf2 ~]# ls -al /etc/init.d/httpd
-rwxr-xr-x  1 root root 3201 Jan 30  2007 /etc/init.d/httpd

[root tf1 log]# ls -al /etc/init.d/httpd
-rwxr-xr-x  1 root root 3201 Jan 30  2007 /etc/init.d/httpd

and the apache service starts/stops just fine on tf2 when the services get failed over to that machine.

any ideas on what can be wrong?

tf1 is complaining about a bad SSL cert.  The fact that it's complaining
when being started by clurgmgrd but not when started manually indicates
that clurgmgrd is starting it differently (specifying a different
httpd.conf file perhaps?).
