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

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.

pyodbc.OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]

Recently, I faced this error in our Docker-Container environment. All the necessary packages were already installed but still, I was facing this clueless error. I search a bit and after an hour and so I found the exact reason and solution for this error. To know more about this error in detail. Please follow this Github thread. https://github.com/mkleehammer/pyodbc/issues/610 https://github.com/mkleehammer/pyodbc/issues/610#issuecomment-587523802 Solution: It's because the   server's certificate has too weak a key. In case you are using Linux env directly/not the Docker one.  Just edited /etc/ssl/openssl.cnf and change these 2 lines. MinProtocol = TLSv1.0 CipherString = DEFAULT@SECLEVEL=1 In case you are also using a container, please add these three lines to your Docker file. RUN chmod +rwx /etc/ssl/openssl.cnf RUN sed -i ' s/TLSv1.2/TLSv1/g ' /etc/ssl/openssl.cnf RUN sed -i ' s/SECLEVEL=2/SECLEVEL=1/g ' /etc/ssl/openssl.cnf Thanks!! Enjoy Programming! Refer...
