Hi Jason,

That’s what I thought. We’ll have a look at the nginx timeout settings then.

Thanks a lot!

Robin

Hi Robin,

I think this is caused by the reverse proxy (nginx) timing out before Tomcat can actually return a response. You might need to have a smaller (or less complex) table , increase the speed of the machine or database server, or have a look at how to increase the timeout for nginx, for instance here (http://howtounix.info/howto/110-connection-timed-out-error-in-nginx)

Best regards,
Jason

Subject: [Dhis2-users] DHIS2 - Communication error "0" when generating pivot table

Hi devs,

Is there a limit on the pivot table size that can be generated in DHIS2? We’re having an extremely large table (in this case used for exporting structured data to excel) with indicators that gives a communication error after generating. When applied for a different period with less data, the table generates normally.

The table contains 1 indicator and 1 data element. When reporting only the data element it’s fine, when reporting only the indicator, it gives an error, which leads me to think there’s a limit to the calculations somewhere.

Any quick ways to fix this?

Kind regards,

Robin
