[jira] [Created] (JENA-515) Incorrectly error message "Currently in
a transaction" when querying SPARQL
Knut-Olav Hoven created JENA-515:
------------------------------------
Summary: Incorrectly error message "Currently in a transaction" when querying SPARQL
Key: JENA-515
URL: https://issues.apache.org/jira/browse/JENA-515
Project: Apache Jena
Issue Type: Bug
Components: TDB
Affects Versions: TDB 0.10.1
Reporter: Knut-Olav Hoven
This has happened after a OutOfMemoryError during import (batched import of 1000 resources per request).
Fetching entire database with curl works OK:
http://localhost:3030/ds/data?graph=sift-tprogram
When querying with SPARQL I get an 500 error "Currently in a transaction".
No other clients are active.
Log output:
