My team conducting a survey can push data to ODK but during pulling of data we get the error below;
Error: retrieving next chunk of instances from server...
NOT ALL SUBMISSIONS RETRIEVED: Error fetching list of submissions: Fetch of
submission download chunk failed. Detailed error: Unexpected
java.net.SocketTimeoutException: Read timed out
Has anyone experienced this too? What more steps can i take to isolate the issue? How can i solve this?
We've already tried to;
- increase tomcat Connection timeout
- increase Java Heap Settings
- increased MySQL interaction and wait timeouts
- Verified network connection to the server
We are currently running ODK Aggregate 1.4.7 on Centos 6.7 , 5GB RAM, MySQL 5.1.73
