UIMA AS: Can't flush CAS, flushing is disabled.
Hello,
I found this warning in my worker node log file, but what does it mean ?
1/5/10 2:21:30 PM - 16:
org.apache.uima.aae.controller.AggregateAnalysisEngineController_impl.replyToClient:
WARNING: CASAdminException: Can't flush CAS, flushing is disabled.
Prior to this warning a Cas Mulitplier throwed a Runtime Exception
(getEmptyCas() was not called yet) from the
next method.
Afterwards the worker node stopped to process CASes on the input queue.
Thanks,
Jörn

Jorn, I was able to replicate your scenario and see that there are actually
two problems:
1) UIMA core fails to reset CAS's lock if there is an exception in an
Annotator's hasNext() or next() method. If there is an exception, the
input CAS remains locked and attempt to reset() the CAS results
in CASAdminException: Can't flush CAS, flushing is disabled.
2) UIMA AS aggregate doesn't return exception to the client if there is a
failure in an aggregate's delegate as described in #1 above.
I will fix both of these tomorrow
Thanks for finding these problems

Re: UIMA AS: Can't flush CAS, flushing is disabled.
Posted by Jaroslaw Cwiklik <ui...@gmail.com>.
Jorn, the NPE exception is coming from your CM as this shows:
org.apache.uima.analysis_engine.impl.PrimitiveAnalysisEngine_impl.callAnalysisComponentNext(512):
SEVERE: Exception occurred
java.lang.NullPointerException
at
dk.infopaq.dtsearch.DocumentRetriever.next(DocumentRetriever.java:114)
The other exceptions are logged by UIMA AnalysisEngine, then by UIMA AS
Error Handler, and finally by the enclosing Aggregate Error Handler.
It looks like UIMA AS is trying to release CAS more than once while handling
the NPE resulting in the
WARNING: CASAdminException: Can't flush CAS, flushing is disabled.
I will look into this

The exception occurs before getEmtpyCas is call, no there is
no cas.reset() call.
There is mistake in the log statement, because the second message
contains {0}.

I think the exception gets logged three times and afterwards
there is the log message of the mentioned warning.
The error repeats a few times, not sure if thats really
the one which causes the hang.
Do you think there is a mistake in the implementation of my Cas Multiplier ?

WARNING: CASAdminException: Can't flush CAS, flushing is disabled.
Re: UIMA AS: Can't flush CAS, flushing is disabled.
Posted by Eddie Epstein <ea...@gmail.com>.
Hi Jorn,
The problem most likely due to the prior Runtime exception. Is there
a stack trace for that? Is the CasMultiplier doing anything strange,
like calling cas.reset()?
Can you send the full stack trace for the other exception?
Regards,
Eddie
