error on big sparql query
Dear all
We increases all memory sizes but still we get errors with sparql insert near 100K....any tip welcome!
Michel
Last week Erwin, Jack and I did some tests with large data. And it seems that the problem related to the memory has gone: Currently we can send in a one big message 90K of values read by sensors but our tests failed with 100k. We don't know the reason, but we think that isn't due to memory because the system has free memory (and it releases it well in each insert request). You can see the status of the server here: http://marmotta.tno.nl:8080/marmotta/core/admin/system.html#mod_System_Statistics
Michel or Jack, could you send to Erwin, Jack and me the server logs in order to detect what is happening when we sent more than 90k messages?.
Regards.
Alberto García Consuegra.

Could be in the database...?
I guess you'd need to run your queries attaching a profiler (e.g., YourKit)
to see find our where the issue is.
