Neven,
You¹re a genius. The web.xml was fine but you got me thinking about spring
configuration.
We had one of our young guys run into an issue with spring. He implemented
some work around and nobody bothered checking because it was minor bit of
code on the periphery of the app.
Anyway I searche

executions, which makes sense.
It looks like I need to find out why the spring config is loaded multiple
times.
I have a context.xml in the META-INF directory which sets up a db
container and jndi datasource realm, could this be the issue?

We have a struts2 based app that uses spiring scheduling to trigger a task
every morning at 6am.
The problem we have is that task in triggered multiple times,
simultaneously.
We have an Ubuntu 14.04.1 Server using the standard tomcat 7 installed using
apt-get and running on oracle java 8.

We use GIT for deployment. This way you are only uploading the delta.
Have a look at how OpenShift does it for the mechanics. I wasn¹t involved
in setting up the system we use but I know the team who did leaned heavily
on what was done on OpenShift.
I can tell you from experience deployments are

Hi Guys,
It's been a while but the nature of this problem means it may be a while
between crashes. But we just had a big one which hung the system and
required a reboot.
I have changed the tomcat options as follows inline with all the advice
and material I read to be as follows:
-server -Xms1460
Thanks Igor,
I just stumbled upon that same document. I think you may be on to
something here.
I have a feeling that the GC may not be configured well.

The move to linux was part of a move in-house for our client as the web

My gut feeling is that the issue isn't related to the WS as they run on a

Hi Edson,
We do have some background threads as we use Quartz for scheduling tasks
but we haven't had any issues with it in the past.
I also checked the monitoring and I'm seeing anything strange during the
execution of the scheduled tasks.

Hi Guys,
We have a application running on the latest Tomcat7 and we are getting a
server crash or becoming unresponsive. This occur every few days at no fixed
intervals or time of day and they certainly don't correlate to any app
function at least not according to the logs.
