<div class="moz-cite-prefix">Hello David and thanks for responding.<br>
I know it supports these event listeners and I use them. In my
program, I have two knowledge agents and the first one
(preprocessing) will read the file, preprocess a DRL and then
write a second modified DRL file in a folder that is monitored by
the second one. When I modify the original DRL file <b>(1.</b> in
prints below<b>)</b> monitored by the preprocessing agent,
everything works fine and the rule is triggered<b> (</b><b>2.)</b>.
However, when I delete a file <b> (</b><b>3.)</b>, the
knowledgeAgent just blocks after AfterChangeSetAppliedEvent and
does not do anything anymore.. If I send new data in the
knowledgeAgent it does not react anymore. <br>
<br>
I would expect to get a stacktrace of what went wrong but I do not
get any info besides of the systemeventlistener or
knowledgeagentlistener. Is there any way I can get a stacktrace?<br>
Kind Regards,<br>

You can do:
kagent.setSystemEventListener( new PrintStreamSystemEventListener() );
kagent.addEventListener( new DebugKnowledgeAgentEventListener( ) );

<pre wrap="">Dear Drools users,
I have been testing with the KnowledgeAgent from version 5.4 and 5.5. It
monitors a changeset and is set to incrementally build the
knowledgebase. I noticed that it sometimes crashes but never throws out
errors. This happens for example when I define a type two times and when
I remove a file. Does anyone experience similar behaviour and has an
idea of how I could see the errors? I already tried to check the errors
by building it myself using a knowledgebuilder before I update the file
that the knowledgeAgent monitors but that's quite a dirty solution.
Kind Regards,
