Component/s:

Native Sail

Affects Version/s:

2.3.0

Fix Version/s:

None

Environment:

running on windows 7
and both java 1.6.0_18 and 1.6.0_17

Description

This issue sounds similar to http://www.openrdf.org/issues/browse/SES-631 and to http://www.openrdf.org/issues/browse/SES-550

we are not able to reproduce it, it happens in the wild. We did not have the issue for the last two years of using previous sesame versions, our software didn't change too much. It may be related to changes done in sesame 2.3.0.

here is the stacktrace:

btw, we solve this problem by:
