Hello,
I have an error that has been popping up randomly since 3 weeks ago and the
randomness of the issue makes it hard to troubleshoot.
I have a service that use the REST API to index documents (1000 docs at a time)
and in this process I often call the core status API
(/solr/admin/cores?action=STATUS) to get the statuses of the different cores.
This process has been working flawlessly since 2014 however it has been failing
recently with the exception: " this IndexWriter is closed".
I did a few search on Google for this exception but I did not see anything
relevant. Does anyone have an idea how to troubleshoot/fix this issue?
This is my configuration:
- Solr 4.10.2 on Windows. I am not using SolrCloud.
- Java 1.7.0_79 24.79-b02
- useColdSearcher is set to true
- maxWarmingSearchers is set to 6
- I changed my Solr configuration about 2-3 months ago: I disabled HTTPS and
enabled the logging (INFO level) but I do not think this could cause the issue.
Relevant stack trace:
