Hi All
My client is receiving a read timeout error when I request large products like
imagery. We made the session timeout error longer (ie 2 min) and still
received the error for certain products (I'm assuming larger ones).
My question is ...
What is the thread execution order for GeoServer products?
For example. My client makes a WPS call to get imagery. If another user makes
a GetCapabilities call, does it stop the WPS call and then resume when the
GetCapabilities call completes? Something like this may be causing the read
timeout error we are receiving.
Here's the error we are seeing
