Apache doesn't start

Hi!

I got a VCS configured with apache web server agent. I tried to put it online (from command line it works) in the cluster and I see the following in the Apache_A.log

2016/06/16 12:45:52 VCS ERROR V-16-10061-20318 Apache:ApacheDMZ:online:<Apache::Start> Could not determine Apache Version.
2016/06/16 12:45:52 VCS ERROR V-16-10061-20133 Apache:ApacheDMZ:online:Failed to online resource

Anyone can tell me why is it? I run "httpd -v" from command line and I see apache version: 2.2.15

Thanks!
