I developed an application in Play Framework 2.4.10 (Java) to run on apache-tomcat servers.
The .war file is created using a plugin of the PlayFramework.
I created a local server apache-tomcat and after the deploy to complete the evolutions happens as expected in all cases, presenting no error logs, only the normal processes of logs. All the functionality of the application works without any kind of error, crashes or lags.
The problem appears when I deploy the application to Google Cloud Platform (GAE) servers and others like my company's.
The deploy happens normally but when the user tries to save new information in some cases the server does not respond to the POST request and the browser is waiting for the response from the server. When the user clicks the save button several times the POST process happens saving the data normally not presenting errors.
Other features such as filtering information, logging out, accessing the registration pages, querying, changing, deleting work normally. The error only occurs when I will update, register or authenticate in the system.
The record screens are made with the templates of the HTML PlayFramework itself with a few hints of the Scala language.
This strange problem happens sporadically.
My form Scala:
@(siteForm: play.data.Form[validators.SiteFormData], paises:Map[String,Boolean])
@import helper._
@import templates.bootstrap._
@views.html.admin.main("Cadastro de Sites") {
<div class="col-md-12">

</div>

}
My Controller:
@Security.Authenticated(SecuredAdmin.class)
public Result inserir(Long id) {
SiteFormData siteData = (id == 0) ? new SiteFormData() : models.Site.makeSiteFormData(id);
//Resgata os dados do formulario atraves de uma requisicao e realiza a validacao dos campos
Form<SiteFormData> formData = Form.form(SiteFormData.class).bindFromRequest();
//se existir erros nos campos do formulario retorne o SiteFormData com os erros
if (formData.hasErrors()) {
formData.reject("Existem erros no formulário");
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
} else {
try {
//Converte os dados do formularios para uma instancia do Site
Site site = Site.makeInstance(formData.get());
//faz uma busca na base de dados do site
Site siteBusca = Ebean.find(Site.class).where().eq("titulo", formData.data().get("titulo")).findUnique();
if (siteBusca != null) {
formData.reject("O Site com o título'" + siteBusca.getTitulo() + "' já esta Cadastrado!");
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
}
site.setDataCadastro(new Date());
site.save();
tipoMensagem = "success";
mensagem = "Site '" + site.getTitulo() + "' cadastrado com sucesso.";
return created(views.html.mensagens.site.mensagens.render(mensagem,tipoMensagem));

Logger.error(e.getMessage());
formData.reject("Erro interno de Sistema. Descrição: " + e);
return badRequest(views.html.admin.sites.create.render(formData, Pais.makePaisMap(siteData)));
}
}
}
