Hi,

Since you’re loading onto localhost, what if you try the data add without the --server-side flag?

3

The stack trace suggests there was a problem with memory allocation. We fixed some issues regarding that in the 5.0-beta release so if you upgrade this problem might go away. Depending on how large data you are trying to add you may want to set the memory configuration option [1] to write_optimized or to bulk_load (latter option introduced in 5.0-beta).

Best,
Evren

I see that you are already using the latest RC release so no need to upgrade. Changing the memory configuration would help but note that you need to restart the server for the change to take effect. We will make some improvements to prevent this error in the future.

Best,
Evren

As you know, I am using the latest RC release.
I doubled the memory setting, and I was able to load the data.

thanks a lot.
