Hi Sebastian,
Are timeout also set anywhere else such as the service/dataset
configuration? If so, they will override the global (server-wide) default.
The 503 message is confusing - it prints the gloabl default (100000ms)
even if the query executed under a different timeout. It looks like it
it set to 3000ms somewhere else as well.

Dear Fuseki users,
I want to use Fuseki 2 for querying various big ontologies, e.g. dbpedia.
However, I have encountered the problem that Fuseki is ignoring the timeout
setting.
I started the server with
./fuseki-server --timeout=100000
which should set the timeout to 100s, but it is rather 3s (see below). I have
seen that there were some discussions regarding the handling of timeouts, but
I'm not sure if this is related to my problem. Here's the log - please note
that I'm using one of the latest snapshot builds (the official 2.0.0 release is
behaving the same way for me):

The problem appears with other queries as well. Sometimes limiting the result set (e.g.
by appending "LIMIT 20" to the SPARQL query) helps.
The system is a quad core virtual machine with 32 GB RAM, running Ubuntu 14.04.
"java -version" is reporting:
OpenJDK Runtime Environment (IcedTea 2.5.4) (7u75-2.5.4-1~trusty1)
OpenJDK 64-Bit Server VM (build 24.75-b04, mixed mode)
I would highly appreciate any advice. I really like Fuseki and would love to
use it for some data mining in medical informatics.
Many thanks,
Sebastian
