CAS service start failed on Ubuntu 14.04

GLUU.root@ce:# service cas start
Starting Jetty: FAILED Tue Jan 17 15:09:12 UTC 2017
GLUU.root@ce:# service cas stop
Stopping Jetty: start-stop-daemon: warning: failed to kill 3386: No such process
1 pids were not killed
No process in pidfile '/var/run/cas.pid' found running; none killed.
OK
GLUU.root@ce:~#

No files in ...../cas/logs/ directory.

@yurem told me, that on redhat the service works well, so the problem is ubuntu-specific.
The problem detected since ~ 3.0.0 beta2. Early builds works well.

PS. CAS will be removed in v3.1 #247.

I fixed this in: bccaee7

It happened when we installed all CE components with 3Gb only: As result java parameters were wrong:
-Xms256m -Xmx153m

After fix:
-Xms128m -Xmx153m

2.Beta3 contains this fix

Also lack of VM memory led to random applications shutdowns when during CE initial we specified more memory than VM can physically allocate.
