Hi everybody.
I am trying to execute the following query
INSERT INTO GRAPH <targetGraph> {
?a <someProperty> ?b
}
WHERE {
GRAPH <sourceGraph> {
?a <someOtherProperty> ?c .
BIND(REPLACE(STR(?a),"something:", "", "i") AS ?b) }
}
The sourceGraph contains about 94 million triplets. When I execute the
above SPARQL, I get no error, however, I get no response either. I check
after some minutes and the <targetGraph> has not yet been created. The
system acts as if I had never executed the statement.
I have tried executing the above through /sparql and through the /conductor
web interfaces.
Is there a way to see what is really going on? Am I doing something wrong?
I have also already tried to debug through the isql-v localhost:8890 dba
<password> -D but I get a totally uncomprehensible error:
isql-v() [0x44986a]
isql-v() [0x4498c8]

isql-v() [0x42fc65]

isql-v() [0x40441e]
GPF: Dkernel.c:3080 can't free if in served sessions
Segmentation fault (core dumped)
Please note that I am using Version: 07.20.3214, Build: Oct 14 2015 on
ubuntu server.
Kind regards,
Pantelis Natsiavas
