Hello!
Today we encountered an error with our application after moving it to a new machine with different resources available to it. According to the cursory research I have done, it looks like the machine has run out of memory for the app to use. This is the error message that was printed to the screen:
Now, I did some testing after moving back to working in my local development environment. It looks like every time I refresh the app’s homepage, it adds about 2 megabytes of memory used.
Before a lot of refreshes:
After a lot of refreshes:
My next course of action was to take a look at any of the variables or objects that might be declared by requesting this page. So, here’s the handler, layout, and view.
Handler:
I should note here, that some of the models injected here also inject one another in their own cfcs.
component {
//Modules/Models
property name = "messageBox" inject="messageBox@cbmessagebox";
property name = "mainHelper" inject="mainHelper";
property name = "sessionsHelper" inject="sessionsHelper";
property name = "userService" inject="userService";
property name = "formManagerHelper" inject="formManagerHelper";
property name = "automailer" inject="automailer";
property name = "auth" inject="authenticationService@cbauth";
/**
* Sets the view to the root of the web application
*/
function index( event, rc, prc )
{
event.paramvalue("msg","");
//These are some messages that could pop up in the index
if(rc.msg == "invalidAuth")
{
messageBox.warn("It looks like you aren't authorized to do that!");
}
else if(rc.msg == "invalidShareToken")
{
messageBox.warn("This sharing link has expired or is invalid. Please get a new share link for this form.");
}
else if(rc.msg == "invalidAccessRequest")
{
messagebox.warn("The share link you tried to access had an invalid access type it tried to share with you.");
}
else if(rc.msg != "")
{
messagebox.warn("It looks like an error occurred: " & rc.msg);
}
//Obtain all of the names of the forms so they can be displayed on the front page
rc.publishedForms = mainHelper.getPublishedForms();
//Obtain the names of the top 4 most submitted forms
rc.mostSubmittedForms = mainHelper.getMostSubmittedForms();
event.setView( "main/index" );
}
.
.
.
}
Layout:
<cfscript>
variables.cbSession = new modules.cbstorages.models.SessionStorage(); //Instantiate cbStorages for Session
</cfscript>

So my question to the community is, am I on the right track? Should I be looking to find instances of where models/modules/variables are declared more than they need to be if I keep adding memory usage every time the page is hit?
In addition, can anyone spot an error I’m making with the addition of more and more memory? It might have something to do with wirebox which I am not well-versed in.
). You didn’t exactly ask for help, so I won’t bother asking for more details, like the JRE version, CF engine/version, ColdBox version, etc.
IMHO it’s much cheaper and easier to increase the RAM usage and get back to writing code/ making 
And then yes, let’s optimize the ColdBox startup as much as possible.
