[rules-users] Drools error log msg?

The reason why I've activated the logging was that some rules are not fired
after inserting a special
amount of facts - in my case exactly 20.
Some more details here:
I work on an Event Correlation & Analysis OSS solution that's based on
Grails & Drools 5.5.0-Final.
I'm using a stateful knowledge session and only call dispose() when the app
is stopped - but all facts
are retracted. The functional testing works fine but as I've mentioned it
before when I run the integration
testing it fails, because rules are not fired ('ClearAlertRule' is not
fired) when I insert more than 20 facts.
I saw the errors in the drools log but I didn't know if they were relevant
for my problem here.
I've attached two picts which document the right and the wrong behavior of
the rule processing
- also I've listed the rules of my rulebase.
Has anybody an idea?
