Nginx: Cannot allocate memory

Recently I faced one weird issue with Nginx and suddenly getting an error on restarting Nginx "Cannot allocate memory" issue as showing in the following image.

When I tried free -g command, memory was available and there was no recent configuration change. Then I started looking into config files and found this line in one of them:

#Working for odoobiz

proxy_cache_path /var/odoo/bzcache/ levels=1:2 keys_zone=my_cache:6000m max_size=6g inactive=60m use_temp_path=off;

Here I was setting more memory - around 6G and available was only 4G for cache, and when I changed the settings to the following, it worked!

#Working for odoobiz

proxy_cache_path /var/odoo/bzcache/ levels=1:2 keys_zone=my_cache:2000m max_size=3g inactive=60m use_temp_path=off;

So, if you are facing any such issue, please check your configuration files and see if somewhere you are allocating more memory then available.

I hope this post will help someone else as well!

Thanks! Enjoy Programming!

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways : 1) using many2one field in both the objects ( http://tutorialopenerp.wordpress.com/2014/04/23/one2one/ ) 2) using inheritance by deligation You can easily find the first solution with little search over internet so let's start with 2nd solution. Scenario : I want to create a one2one relation between two objects of openerp hr.employee and hr.employee.medical.details What I should do i. Add _inherits section in hr_employee class ii.

How to draw Dynamic Line or Timeseries Chart in Java using jfreechart library?

Today we are going to write a code to draw a dynamic timeseries-cum-line chart in java. The only difference between simple and dynamic chart is that a dynamic event is used to create a new series and update the graph. In out example we are using timer which automatically calls a funtion after every 1/4 th second and graph is updated with random data. Let's try with the code : Note : I had tried my best to provide complete documentation along with code. If at any time anyone have any doubt or question please post in comments section. DynamicLineAndTimeSeriesChart.java import java.awt.BorderLayout; import java.awt.Color; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.Timer; import javax.swing.JPanel; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.plot.XYPlot; import

Flickr and OAuth

What is Flickr? I think you landed on this page because you know what Flickr is, so let’s come to the point and discuss about the API. Why am explaining? Although each and everything, about API, is well documented on Flickr website here , I'm just trying to explain the whole process by dividing it into small parts. Old Authentication API The current Flickr authorization scheme is not the first one it used. In the early days of Flickr, users granted the power to an app to act on their behalf by giving the apps their Flickr username and password. Doing so meant that in order to revoke an app’s permission, users would have to change their Flickr password. Of course, doing that would also instantly revoke permissions of other third-party apps with knowledge of the user’s password. The new authorization scheme is meant to correct obvious problems with the old scheme. Why should you as a user have to use your Flickr password for anything other than your dealings with Flickr?
