Socket Read timeouts in google-api-java-client #733

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Version of google-api-java-client - 1.10.2

Java environment - Java 6

Starting December 2012, we are noticing some socket read timeouts in the Google 
java client google-api-client-1.10.2 in requests that fetch events from a 
single calendar. This does not happen for all requests but some fraction of 
requests. The client code on our end fetches all calendars for a user and 
spawns separate request threads to fetch events from each calendar in parallel. 
The outgoing requests go through a company firewall and a proxy server before 
reaching Google.

The stack trace is -
Caused by: java.net.SocketTimeoutException: Read timed out

Any pointers in troubleshooting will be helpful. What is the likely cause for 
the connection break/timeout? 

Thanks
