[rules-users] No errors thrown from KnowledgeAgent

[De Rooms Brecht]

Hello David and thanks for responding.
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 *(1.* in prints below*)* monitored by the preprocessing agent, 
everything works fine and the rule is triggered*(**2.)*. However, when I 
delete a file *(**3.)*, 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.

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?
Kind Regards,
De Rooms Brecht
