Hello everyone,
Recently I'm using Drools in a multithreaded environment. But after a while I
see that Drools is running for endless time even though I gave him with
fireAllRules(1000) a limitation to fire only 1000 rules. The occurrence is
rule-independent, I've checked multiple times and each time it's another rule
which works well if I run it separately.
Could someone check the code of this stack trace? That's a thread dump of my
last run.

Also here the rule and code snipped I'm using to prove that the infinite loop
does not come from my code:
//kSession is a StatefulKnowledgeSession
try {
//Limiting the Activation will prevent infinite loops
kSession.fireAllRules(1000);
} catch (Exception e) {
System.out.println("error while processing :: " + e.toString());
System.out.println(rule);
} finally {
kSession.dispose();
}

rule "308"
no-loop
when
$0:NormalizedNamedEntity(
ct_0:CoveredText,
cp_0:Concept,
label_0:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("ops"))
$1:NormalizedNamedEntity(
ct_1:CoveredText,
cp_1:Concept,
label_1:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("bodyside"))
then
int start = getStart($0,$1);
int ende = getStop($0,$1);
String attribute = label_0+" "+label_1;
insert(annotate(aJCas, "Operation", 309, attribute, start, ende, "",
attribute));
end
I appreciate any help to solve this occurrence.
Greetings
Bojan
