RejectedExecutionException when shutttingdown corecontainer

[NarasimhaRaju <ra...@yahoo.com>]

Hi,

I am using solr 1.3 and when indexing i am getting RejectedExecutionException after processing the last batch of update records from the database.
happening when coreContainer.shutdown() is called after processing the last record.
i have autocommits enabled based on maxTime which is 10 minutes.

from the exception below i see it's happening from commitTracker of DefaultUpdateHandler2.

looking at the SolrCore.close method searchExecutor.shutdown() is called before updateHandler.close()

I still don't understand why updateHandler is called after searchExcecutor when updateHandler has the possibility of adding/submitting to searchExecutor.

is this a bug or am i doing something wrong with my autocommit.

Sorry for such a late reply...

: I still don't understand why updateHandler is called after 
: searchExcecutor when updateHandler has the possibility of 
: adding/submitting to searchExecutor.

...i believe you are correct, this does look like a race condition bug.  

I've opened SOLR-2008 to track fixing this...
https://issues.apache.org/jira/browse/SOLR-2008

Thanks for bringing this up!
