Hi all,

If it can help, you can find attached the error that I got in the collectory.

Cheers,
Marie

Hi Tim, all,

Unfortunately, the error occurs before the beginning of the loading. You can find below the logging track when I executed "biocache load -dr179" command. The error comes from the upload, I got the same error when I tried to access this URL : http://metadonnee.gbif.fr/upload/1464722424642/75956ee6-1a2b-4fa3-b3e8-ccda64ce6c2d.zip

The VM that hosts the collectory modules, used to have 4Go of RAM. I asked if it was possible to increase it (for a limited time) and I have got 32 Go, now. Even with this increase of memory, we still got the error. 

Thanks for your answer,
Cheers,
Marie

Hi Marie


Do you see any output at all?  E.g. Are there log lines like:
  1000 >> last key : 123, UUID: Š records per sec: 4567
  2000 >> last key : 423, UUID: Š records per sec: 4568

As far as I can tell, the code [1] is using the usual GBIF DwC-A Reader
which is just an iterator and should not use significant memory for that.

I notice it appears to be batching [2].  I am not familiar with that code
but I¹d expect to find config for a batch size, and perhaps if it is not
set it might default to unlimited?

The DwC-A reader also handles pre-deflated zips (i.e. A directory, not a
zip file).  You could try unzipping it using standard tools and then
rather than using a URL, reference a local directory so that it calls the
loadLocal [3] instead of downloading, unzipping and then loading which is
what a URL will invoke.

I¹m sorry I have not loaded a large file myself, but I know it should be
possible.

I hope this helps provide some ideas at least.

Many thanks,
Tim
