There is work-in-progress to improve configuration : JENA-1731.
This includes setting context on endpoint and dataset as well as

I’m surprised that the query you indicate works in 3.9.0. It looks like what’s
intended is a phrase query but it needs to be surrounded by double

Rajiv,
I have failed to reproduce this. I ran a Fuseki server and sent 1000's
of ASK queries to it. No threads were created.
I used quite simple ASK queries - maybe there is complexity in queryStr?
The results of an ASK query are about 400 bytes on the wire, including
HTTP header - that fi

Setting the query time may reduce the general effect but it will not free
up threads. A query timeout is a graceful abort of the query - the query
gets a chance to clean up and that needs the query execution in the server
getting called.

Hi Rajiv,
You can find how to set query timeouts in the Fuseki documentation at [1]
To set server wide timeout:
[] rdf:type fuseki:Server ;
#Server-wide context parameters can be given here.
#For example, to set query timeouts: on a server-wide basis:
#Format 1: "10
Hi,
Our application which is running at Tomcat server is making query to Fuseki
TDB store using HTTP protocol.
We have observed that thread count for the Fuseki process is increasing
with time.
I know there might be code issue and resources should be closed properly.
