BoM SOS Stream Guages timeseries often does not work - BoM Tomcat OutOfMemoryError #59

Closed meh9 closed 2 years ago

meh9 commented 4 years ago

When trying to use the BoM Stream Guages data, when you click on a station on the map, the timeseries often shows the preview in the feature info popup, but when you click Expand you get a 500 Server Error 95% of the time.

E.g. this URL: https://maps.dea.ga.gov.au/#share=s-qPKEFkC0bO1Ztq99QLAMutiONmW

Clicking on the point (sometimes doesn't work, may have to click again):

Looking at what happens on the request, it's actually a Tomcat OutOfMemoryError:

This is actually a problem with the data service from BoM - we should raise it with them.
