Stardog query fails with error on console but works with stardog frontend

[mayurb...@gmail.com]

Hello,
I am running a query which  works fine when running on Stardog admin console UI, but when the same query is run through command it fails with ArrayIndexOutOfBounds exception.
Any idea what could be the possible issue ?

Thanks you,
Mayur

Can you send the output from stardog.log and the version you're running?

Hi,

This is the error observed in the logs. Surprisingly when I restarted the server the error vanished and query also worked fine.
Any thoughts what could be the possible reason and how to avoid such situations.
