Dear Scott, I am currently using TBCME 4.6.3 (trial) in a RedHat Enterprise Linux 6.6 (Santiago) environment with an 8GB Xmx. Composer crashes reliably when clicking the "Source Code" tab on a 60MB .ttl ontology (the .ttl version of chebi.owl).

Cheers,

Christian

Hi Christian,

with "crashing" do you mean it just quits or is there any error message? Also, which resource is selected when you switch to the Source Code tab - are you still at the owl:Ontology instance or did you navigate to some "large" resource?

For very large files please consider usin the "streaming loader" Import wizard to TDB - obviously there are memory limitations at some stage with Turtle files.

Thanks
Holger

TBC just quits, no error message, no nothing. This happens regardless of the currently selected entity/resource, hence it also happens at the owl:Ontology instance.

To replicate this: (1) download chebi.owl, (2) import it into TBC, (3) turn it into .ttl (patience as it takes a while), (4) delete the original .owl file, (5) load the .ttl file, (6) navigate to some entity (or just stay on the Ontology form), and finally, (7) click the "Source Code" tab.

Followup: tried opening chebi.ttl in TBC's text editor with the same outcome--namely TBC crashes/quits. It may be that the text editor that comes with TBC cannot handle large files. Will give your "streaming loader" idea a try. (Note that Linux's gedit doesn't seem to have a problem with the .ttl file.)

Hi Christian,

When you can please send this TBC log file. Thanks.

I could find no .log file at the location you indicated. (Yes, I have displayed hidden files and all that. Also, I imagine that by "TBCMEWorkspace" you mean my (currently one and only) TBC workspace, right?) Alternatively, I could upload the chebi.ttl file to the cloud, so you could take a stab at it yourself.

Cristian, if you can’t find the log file, you could open TBC, select Window > Show View menu and click on the Error Log. Once this view opens, one of its menu items allows you to save the log into a location of your choice.

The "Error Log" is clean, which is maybe why there is no log file on the hard drive in the first place. No error entry is generated following the crash.

Same behavior noticed when clicking on the "SPARQL" tab: TBC quits abruptly, with no error message. Again, looks like a text editor issue to me.
