Failure - abandoned all retry attempts [Export JSON]

Development
1

JSON Export was working just fine but with the increase in the number of
submitted forms i'm now getting this error message: Failure - abandoned all
retry attempts

There is nothing in the logfile, I'm using Apache Tomcat 6.

any help is appreciated,
Cheers

There should be something in one of the log files. I believe the logging
mostly goes to tomcat6-stdout (and not catalina) -- look at the other
files in the logs directory.

It is likely that you are running out of virtual memory.

The export function assembles the entire JSON file in memory before writing
it to the database.

If you have enough DRAM, increasing the Tomcat JVM size should allow the
entire file to be constructed.

As datasets grow and you run out of DRAM on your system, we provide the
publishers and ODK Briefcase to access those larger datasets.

If you find you have reached the limits of the server, you might consider
extending ODK Briefcase to implement an Export to JSON functionality. If
you do that, please consider contributing those changes back to the
community under the Apache 2 license.
